Detailed Description

A viewpoint from which the scene will be rendered.

Remarks
OGRE renders scenes from a camera viewpoint into a buffer of some sort, normally a window or a texture (a subclass of RenderTarget). OGRE cameras support both perspective projection (the default, meaning objects get smaller the further away they are) and orthographic projection (blueprint-style, no decrease in size with distance). Each camera carries with it a style of rendering, e.g. full textured, flat shaded, wireframe), field of view, rendering distances etc, allowing you to use OGRE to create complex multi-window views if required. In addition, more than one camera can point at a single render target if required, each rendering to a subset of the target, allowing split screen and picture-in-picture views.
Cameras maintain their own aspect ratios, field of view, and frustum, and project co-ordinates into a space measured from -1 to 1 in x and y, and 0 to 1 in z. At render time, the camera will be rendering to a Viewport which will translate these parametric co-ordinates into real screen co-ordinates. Obviously it is advisable that the viewport has the same aspect ratio as the camera to avoid distortion (unless you want it!).
Starting Ogre 2.x, a Camera must be attached to a SceneNode, using the method SceneNode::attachObject. By default the camera is attached to the root scene node on creation. When this is done the Camera will combine it's own position/orientation settings with it's parent SceneNode. This is also useful for implementing more complex Camera / object relationships i.e. having a camera attached to a world object.

Member Typedef Documentation

◆ CustomParameterMap

typedef map<size_t, Vector4>::type Ogre::Renderable::CustomParameterMap
inherited

◆ MovableObjectArray

@See SceneManager::cullFrustum

Remarks
We don't pass by reference on purpose (avoid implicit aliasing) We perform frustum culling AND test visibility mask at the same time
Parameters
frustumFrustum to clip against
sceneVisibilityFlagsCombined scene's visibility flags (i.e. viewport | scene). Set LAYER_SHADOW_CASTER bit if you want to exclude non-shadow casters.
outCulledObjectsOut. List of objects that are (fully or partially) inside the frustum and should be rendered
lodCameraCamera in which lod levels calculations are based (i.e. during shadow pass renders) Note however, we only use this camera to calulate if should be visible according to mUpperDistance

Member Enumeration Documentation

◆ CameraSortMode

Sets how the objects are sorted.

This affects both opaque (performance optimization, rendered front to back) and transparents (visual correctness, rendered back to front)

Object sorting is approximate, and some scenes are suited to different modes depending on the objects' geometric properties

See https://forums.ogre3d.org/viewtopic.php?f=2&t=94090 for examples

Please note that RenderQueue::addRenderable quantizes the final depth value. Therefore if two objects are numerically very close, the chosen mode may not make too much of a difference.

Enumerator
SortModeDistance 

Sort objects by distance to camera.

i.e. cameraPos.distance( objPos ) - objRadius

The bigger the object radius, the closer it is considered to be to the camera

SortModeDepth 

Sort objects by depth i.e.

objViewSpacePos.z - objRadius

The bigger the object radius, the closer it is considered to be to the camera

SortModeDistanceRadiusIgnoring 

Same as SortModeDistance, but skips object radius from calculations.

SortModeDepthRadiusIgnoring 

Same as SortModeDepth, but skips object radius from calculations.

Remarks
Do not attempt to render a Renderable whose datablock has been set to null. It will crash. You can call setDatablock afterwards though. Use at your own risk, hence the _underscore. See http://ogre3d.org/forums/viewtopic.php?f=25&t=91791&p=534476#p534476

◆ _updateCustomGpuParameter()

virtual void Ogre::Renderable::_updateCustomGpuParameter ( const GpuProgramParameters_AutoConstantEntry constantEntry,
GpuProgramParameters params 
) const
virtualinherited

Update a custom GpuProgramParameters constant which is derived from information only this Renderable knows.

Remarks
This method allows a Renderable to map in a custom GPU program parameter based on it's own data. This is represented by a GPU auto parameter of ACT_CUSTOM, and to allow there to be more than one of these per Renderable, the 'data' field on the auto parameter will identify which parameter is being updated. The implementation of this method must identify the parameter being updated, and call a 'setConstant' method on the passed in GpuProgramParameters object, using the details provided in the incoming auto constant setting to identify the index at which to set the parameter.
You do not need to override this method if you're using the standard sets of data associated with the Renderable as provided by setCustomParameter and getCustomParameter. By default, the implementation will map from the value indexed by the 'constantEntry.data' parameter to a value previously set by setCustomParameter. But custom Renderables are free to override this if they want, in any case.
Parameters
constantEntryThe auto constant entry referring to the parameter being updated
paramsThe parameters object which this method should call to set the updated parameters.

Reimplemented in Ogre::v1::SubEntity.

◆ _updateRenderQueue()

virtual void Ogre::MovableObject::_updateRenderQueue ( RenderQueue queue,
Camera camera,
const Camera lodCamera 
)
inlinevirtualinherited

Remarks
The engine will call this method when this object is to be rendered. The object must then create one or more Renderable subclass instances which it places on the passed in Queue for rendering.

Reimplemented in Ogre::v1::StaticGeometry::Region, Ogre::ParticleSystem, Ogre::v1::ManualObject, Ogre::Light, Ogre::v1::Entity, Ogre::v1::BillboardSet, Ogre::MovablePlane, and Ogre::v1::BillboardChain.

Disables any custom near clip plane.

◆ disableReflection()

virtual void Ogre::Frustum::disableReflection ( void  )
virtualinherited

Disables reflection modification previously turned on with enableReflection.

◆ enableCustomNearClipPlane() [1/2]

virtual void Ogre::Frustum::enableCustomNearClipPlane ( const MovablePlane plane)
virtualinherited

Links the frustum to a custom near clip plane, which can be used to clip geometry in a custom manner without using user clip planes.

Remarks
There are several applications for clipping a scene arbitrarily by a single plane; the most common is when rendering a reflection to a texture, and you only want to render geometry that is above the water plane (to do otherwise results in artefacts). Whilst it is possible to use user clip planes, they are not supported on all cards, and sometimes are not hardware accelerated when they are available. Instead, where a single clip plane is involved, this technique uses a 'fudging' of the near clip plane, which is available and fast on all hardware, to perform as the arbitrary clip plane. This does change the shape of the frustum, leading to some depth buffer loss of precision, but for many of the uses of this technique that is not an issue.
This version of the method links to a plane, rather than requiring a by-value plane definition, and therefore you can make changes to the plane (e.g. by moving / rotating the node it is attached to) and they will automatically affect this object.
Note
This technique only works for perspective projection.
Parameters
planeThe plane to link to to perform the clipping. This plane must continue to exist while the camera is linked to it; do not destroy it before the frustum.

◆ enableCustomNearClipPlane() [2/2]

virtual void Ogre::Frustum::enableCustomNearClipPlane ( const Plane plane)
virtualinherited

Links the frustum to a custom near clip plane, which can be used to clip geometry in a custom manner without using user clip planes.

Remarks
There are several applications for clipping a scene arbitrarily by a single plane; the most common is when rendering a reflection to
a texture, and you only want to render geometry that is above the water plane (to do otherwise results in artefacts). Whilst it is possible to use user clip planes, they are not supported on all cards, and sometimes are not hardware accelerated when they are available.

Note

Parameters
planeThe plane to link to to perform the clipping. This plane must continue to exist while the camera is linked to it; do not destroy it before the frustum.

◆ enableReflection() [1/2]

virtual void Ogre::Frustum::enableReflection ( const MovablePlane p)
virtualinherited

Modifies this frustum so it always renders from the reflection of itself through the plane specified.

Note that this version of the method links to a plane so that changes to it are picked up automatically. It is important that this plane continues to exist whilst this object does; do not destroy the plane before the frustum.

Remarks
This is obviously useful for performing planar reflections.

◆ getProjectionMatrix()

virtual const Matrix4& Ogre::Frustum::getProjectionMatrix ( void  ) const
virtualinherited

Gets the normal projection matrix for this frustum, ie the projection matrix which conforms to standard right-handed rules and uses depth range [-1,+1].

Remarks
This differs from the rendering-API dependent getProjectionMatrixRS in that it always returns a right-handed projection matrix with depth range [-1,+1], result no matter what rendering API is being used - this is required for some uniform algebra for example.

◆ getProjectionMatrixWithRSDepth()

virtual const Matrix4& Ogre::Frustum::getProjectionMatrixWithRSDepth ( void  ) const
virtualinherited

Gets the depth-adjusted projection matrix for the current rendersystem, but one which still conforms to right-hand rules.

Remarks
This differs from the rendering-API dependent getProjectionMatrix in that it always returns a right-handed projection matrix result no matter what rendering API is being used - this is required for vertex and fragment programs for example. However, the resulting depth range may still vary between render systems since D3D uses [0,1] and GL uses [-1,1], and the range must be kept the same between programmable and fixed-function pipelines.

◆ getProjectionParamsAB()

Vector2 Ogre::Frustum::getProjectionParamsAB ( void  ) const
inherited

Returns the terms projectionA and projectionB in .x and .y respectively, which can be used to reconstruct linear depth from a Z buffer with the following formula: linearDepth = projectionParams.y / (fDepth - projectionParams.x);.

Gets the camera's up vector.

◆ getUseIdentityProjection()

bool Ogre::Renderable::getUseIdentityProjection ( void  ) const
inlineinherited

Returns whether or not to use an 'identity' projection.

Remarks
Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not change this.
See also
Renderable::setUseIdentityProjection

◆ getUseIdentityView()

bool Ogre::Renderable::getUseIdentityView ( void  ) const
inlineinherited

Returns whether or not to use an 'identity' view.

Remarks
Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normal renderables need not change this.
See also
Renderable::setUseIdentityView

◆ getUseIdentityViewProjMatrixIsDynamic()

virtual bool Ogre::Renderable::getUseIdentityViewProjMatrixIsDynamic ( void  ) const
inlinevirtualinherited

Returns whether the Hlms implementation should evaluate getUseIdentityProjection per object at runtime, or if it can assume the Renderable will remain with the same setting until the datablock is flushed (performance optimization)

Remarks
Hlms implementations may ignore this setting (e.g. assume always true or always false) or even not support identity matrix overrides at all. For example currently Unlit supports them all, but will assume this returns always true if getUseIdentityWorldMatrix returns false.

◆ getUseIdentityWorldMatrix()

virtual bool Ogre::Renderable::getUseIdentityWorldMatrix ( void  ) const
inlinevirtualinherited

Returns whether the world matrix is an identity matrix.

Remarks
It is up to the Hlms implementation whether to honour this request. Take in mind changes of this value at runtime may not be seen until the datablock is flushed. It is implemented as a virtual call because this functionality isn't required very often (hence we save per-Renderable space for those that don't use it) and this function will be called at creation time to use a different shader; not during rendering time per Renderable.

Reimplemented in Ogre::v1::BillboardSet.

◆ getUseMinPixelSize()

inlineinherited

◆ getViewMatrix() [1/2]

const Matrix4& Ogre::Camera::getViewMatrix ( bool  ownFrustumOnly) const

Specialised version of getViewMatrix allowing caller to differentiate whether the custom culling frustum should be allowed or not.

Remarks
The default behaviour of the standard getViewMatrix is to delegate to the alternate culling frustum, if it is set. This is expected when performing CPU calculations, but the final rendering must be performed using the real view matrix in order to display the correct debug view.

◆ pitch()

void Ogre::Camera::pitch ( const Radian angle)

Pitches the camera up/down anticlockwise around it's local z axis.

◆ postRender()

virtual void Ogre::Renderable::postRender ( SceneManager sm,
RenderSystem rsys 
)
inlinevirtualinherited

Called immediately after the Renderable has been rendered.

◆ preRender()

virtual bool Ogre::Renderable::preRender ( SceneManager sm,
RenderSystem rsys 
)
inlinevirtualinherited

Called just prior to the Renderable being rendered.

Remarks
OGRE is a queued renderer, so the actual render commands are executed at a later time than the point at which an object is discovered to be visible. This allows ordering & grouping of renders without the discovery process having to be aware of it. It also means OGRE uses declarative render information rather than immediate mode rendering - this is very useful in that certain effects and processes can automatically be applied to a wide range of scenes, but the downside is that special cases are more difficult to handle, because there is not the declared state to cope with it.
This method allows a Renderable to do something special at the actual point of rendering if it wishes to. When this method is called, all the material render state as declared by this Renderable has already been set, all that is left to do is to bind the buffers and perform the render. The Renderable may modify render state itself if it wants to (and restore it in the postRender call) before the automated render happens, or by returning 'false' from this method can actually suppress the automatic render and perform one of its own.
Returns
true if the automatic render should proceed, false to skip it on the assumption that the Renderable has done it manually.

Reimplemented in Ogre::v1::BillboardChain.

◆ projectSphere()

bool Ogre::Camera::projectSphere ( const Sphere sphere,
Real left,
Real top,
Real right,
Real bottom 
) const

inlineinherited

Gets a list of lights, ordered relative to how close they are to this movable object.

Remarks
The lights are filled in

Returns
The list of lights use to lighting this object.

◆ removeCustomParameter()

void Ogre::Renderable::removeCustomParameter ( size_t  index)
inlineinherited

Removes a custom value which is associated with this Renderable at the given index.

Parameters
indexIndex of the parameter to remove.
See also
setCustomParameter for full details.

◆ removeListener()

virtual void Ogre::Camera::removeListener ( Listener l)
virtual

Remove a listener to this camera.

◆ removeQueryFlags()

inlineinherited

As setQueryFlags, except the flags passed as parameters are removed from the existing flags on this object.

◆ removeVisibilityFlags()

inlineinherited

As setVisibilityFlags, except the flags passed as parameters are removed from the existing flags on this object.

◆ resetFrustumExtents()

virtual void Ogre::Frustum::resetFrustumExtents ( )
virtualinherited

Reset the frustum extents to be automatically derived from other params.

◆ resetWindow()

virtual void Ogre::Camera::resetWindow ( void  )
virtual

Cancel view window.

◆ roll()

void Ogre::Camera::roll ( const Radian angle)

Rolls the camera anticlockwise, around its local z axis.

◆ rotate() [1/2]

void Ogre::Camera::rotate ( const Quaternion q)

Rotate the camera around an arbitrary axis using a Quaternion.

◆ rotate() [2/2]

void Ogre::Camera::rotate ( const Vector3 axis,
const Radian angle 
)

Rotate the camera around an arbitrary axis.

◆ setAspectRatio()

virtual void Ogre::Frustum::setAspectRatio ( Real  ratio)
virtualinherited

Sets the aspect ratio for the frustum viewport.

Remarks
The ratio between the x and y dimensions of the rectangular area visible through the frustum is known as aspect ratio: aspect = width / height .
The default for most fullscreen windows is 1.3333 - this is also assumed by Ogre unless you use this method to state otherwise.

◆ setAutoAspectRatio()

void Ogre::Camera::setAutoAspectRatio ( bool  autoratio)

If set to true a viewport that owns this frustum will be able to recalculate the aspect ratio whenever the frustum is resized.

Remarks
You should set this to true only if the frustum / camera is used by one viewport at the same time. Otherwise the aspect ratio for other viewports may be wrong.

◆ setAutoTracking()

void Ogre::Camera::setAutoTracking ( bool  enabled,
SceneNode *const  target = 0,
const Vector3 offset = Vector3::ZERO 
)

Enables / disables automatic tracking of a SceneNode.

Remarks
If you enable auto-tracking, this Camera will automatically rotate to look at the target SceneNode every frame, no matter how it or SceneNode move. This is handy if you want a Camera to be focused on a single object or group of objects. Note that by default the Camera looks at the origin of the SceneNode, if you want to tweak this, e.g. if the object which is attached to this target node is quite big and you want to point the camera at a specific point on it, provide a vector in the 'offset' parameter and the camera's target point will be adjusted.
Parameters
enabledIf true, the Camera will track the SceneNode supplied as the next parameter (cannot be null). If false the camera will cease tracking and will remain in it's current orientation.
targetPointer to the SceneNode which this Camera will track. Make sure you don't delete this SceneNode before turning off tracking (e.g. SceneManager::clearScene will delete it so be careful of this). Can be null if and only if the enabled param is false.
offsetIf supplied, the camera targets this point in local space of the target node instead of the origin of the target node. Good for fine tuning the look at point.

◆ setCastShadows()

void Ogre::MovableObject::setCastShadows ( bool  enabled)
inlineinherited

Sets whether or not this object will cast shadows.

Remarks
This setting simply allows you to turn on/off shadows for a given object. An object will not cast shadows unless the scene supports it in any case (see SceneManager::setShadowTechnique), and also the material which is in use must also have shadow casting enabled. By default all entities cast shadows. If, however, for some reason you wish to disable this for a single object then you can do so using this method.
Note
This method normally refers to objects which block the light, but since Light is also a subclass of MovableObject, in that context it means whether the light causes shadows itself.

◆ setCullingFrustum()

void Ogre::Camera::setCullingFrustum ( Frustum frustum)
inline

Tells the camera to use a separate Frustum instance to perform culling.

Remarks
By calling this method, you can tell the camera to perform culling against a different frustum to it's own. This is mostly useful for debug cameras that allow you to show the culling behaviour of another camera, or a manual frustum instance.
Parameters
frustumPointer to a frustum to use; this can either be a manual Frustum instance (which you can attach to scene nodes like any other MovableObject), or another camera. If you pass 0 to this method it reverts the camera to normal behaviour.

◆ setCustomParameter()

void Ogre::Renderable::setCustomParameter ( size_t  index,
const Vector4 value 
)
inlineinherited

Sets a custom parameter for this Renderable, which may be used to drive calculations for this specific Renderable, like GPU program parameters.

Remarks
Calling this method simply associates a numeric index with a 4-dimensional value for this specific Renderable. This is most useful if the material which this Renderable uses a vertex or fragment program, and has an ACT_CUSTOM parameter entry. This parameter entry can refer to the index you specify as part of this call, thereby mapping a custom parameter for this renderable to a program parameter.
Parameters
indexThe index with which to associate the value. Note that this does not have to start at 0, and can include gaps. It also has no direct correlation with a GPU program parameter index - the mapping between the two is performed by the ACT_CUSTOM entry, if that is used.
valueThe value to associate.

◆ setCustomProjectionMatrix()

virtual void Ogre::Frustum::setCustomProjectionMatrix ( bool  enable,
const Matrix4 projectionMatrix = Matrix4::IDENTITY,
bool  alternateDepthRange = false 
)
virtualinherited

Set whether to use a custom projection matrix on this frustum.

Remarks
This is an advanced method which allows you to manually set the projection matrix on this frustum, rather than having it calculate itself based on the clipping distances or the field of view.

See Frustum::setCustomViewMatrix

Note
After enabling a custom projection matrix, the frustum will no longer update on its own based on field of view and near / far distance changes. You are completely responsible for keeping the projection matrix up to date if those values change. The custom matrix will be returned from getProjectionMatrix and derivative functions. Even when using a custom projection matrix, you should still call the methods that update the ner / far distances and field of view.
Parameters
enableIf true, the custom projection matrix passed as the second parameter will be used in preference to an auto calculated one. If false, the frustum will revert to auto calculating the projection matrix.
projectionMatrixThe custom view matrix to use.
alternateDepthRangeSet this to true if the input projectionMatrix has the depth in range [0; 1] instead of the range [-1; 1] that Ogre expects.

Projection matrices obtained from Oculus SDK's need to set this to true.

Note that we will internally convert the projection matrix by performing the range conversion, so don't expect Frustum::getProjectionMatrix to return you exactly the same projection matrix you passed to us!

◆ setCustomViewMatrix()

virtual void Ogre::Frustum::setCustomViewMatrix ( bool  enable,
const Matrix4 viewMatrix = Matrix4::IDENTITY 
)
virtualinherited

Set whether to use a custom view matrix on this frustum.

Remarks
This is an advanced method which allows you to manually set the view matrix on this frustum, rather than having it calculate itself based on it's position and orientation.
Note
After enabling a custom view matrix, the frustum will no longer update on its own based on position / orientation changes. You are completely responsible for keeping the view matrix up to date. The custom matrix will be returned from getViewMatrix.
Parameters
enableIf true, the custom view matrix passed as the second parameter will be used in preference to an auto calculated one. If false, the frustum will revert to auto calculating the view matrix.
viewMatrixThe custom view matrix to use, the matrix must be an affine matrix.

◆ setDatablock() [2/2]

void Ogre::Renderable::setDatablock ( IdString  datablockName)
inherited

Assigns a datablock (i.e.

HLMS material) based on its unique name.

Remarks
An null IdString() is valid, it will use the default material

◆ setDatablockOrMaterialName()

void Ogre::Renderable::setDatablockOrMaterialName ( String  materialName,
String  groupName 
)
inherited

First tries to see if an HLMS datablock exist with the given name, if not, tries to search among low level materials.

◆ setDefaultLightMask()

static void Ogre::MovableObject::setDefaultLightMask ( uint32  mask)
inlinestaticinherited

Set the default light mask for all future MovableObject instances.

◆ setDefaultQueryFlags()

static void Ogre::MovableObject::setDefaultQueryFlags ( uint32  flags)
inlinestaticinherited

Set the default query flags for all future MovableObject instances.

◆ setDefaultRenderQueueSubGroup()

static void Ogre::Renderable::setDefaultRenderQueueSubGroup ( uint8  subGroup)
inlinestaticinherited

Sets the default render queue sub group for all future Renderable instances.

◆ setDefaultSortMode()

static void Ogre::Camera::setDefaultSortMode ( CameraSortMode  sortMode)
inlinestatic

Sets the default sort mode for all future Camera instances.

◆ setDefaultVisibilityFlags()

static void Ogre::MovableObject::setDefaultVisibilityFlags ( uint32  flags)
inlinestaticinherited

Set the default visibility flags for all future MovableObject instances.

◆ setDirection() [1/2]

void Ogre::Camera::setDirection ( const Vector3 vec)

Sets the camera's direction vector.

◆ setDirection() [2/2]

void Ogre::Camera::setDirection ( Real  x,
Real  y,
Real  z 
)

Sets the camera's direction vector.

Remarks
Note that the 'up' vector for the camera will automatically be recalculated based on the current 'up' vector (i.e. the roll will remain the same).

◆ setFarClipDistance()

virtual void Ogre::Frustum::setFarClipDistance ( Real  farDist)
virtualinherited

Sets the distance to the far clipping plane.

Remarks
The view frustum is a pyramid created from the frustum position and the edges of the viewport. This method sets the distance for the far end of that pyramid. Different applications need different values: e.g. a flight sim needs a much further far clipping plane than a first-person shooter. An important point here is that the larger the ratio between near and far clipping planes, the lower the accuracy of the Z-buffer used to depth-cue pixels. This is because the Z-range is limited to the size of the Z buffer (16 or 32-bit) and the max values must be spread over the gap between near and far clip planes. As it happens, you can affect the accuracy far more by altering the near distance rather than the far distance, but keep this in mind.
Parameters
farDistThe distance to the far clipping plane from the frustum in world coordinates.If you specify 0, this means an infinite view distance which is useful especially when projecting shadows; but be careful not to use a near distance too close.

◆ setFixedYawAxis()

void Ogre::Camera::setFixedYawAxis ( bool  useFixed,
const Vector3 fixedAxis = Vector3::UNIT_Y 
)

Tells the camera whether to yaw around it's own local Y axis or a fixed axis of choice.

Remarks
This method allows you to change the yaw behaviour of the camera
  • by default, the camera yaws around a fixed Y axis. This is often what you want - for example if you're making a first-person shooter, you really don't want the yaw axis to reflect the local camera Y, because this would mean a different yaw axis if the player is looking upwards rather than when they are looking straight ahead. You can change this behaviour by calling this method, which you will want to do if you are making a completely free camera like the kind used in a flight simulator.
Parameters
useFixedIf true, the axis passed in the second parameter will always be the yaw axis no matter what the camera orientation. If false, the camera yaws around the local Y.
fixedAxisThe axis to use if the first parameter is true.

◆ setFocalLength()

virtual void Ogre::Frustum::setFocalLength ( Real  focalLength = 1.0)
virtualinherited

Sets frustum focal length (used in stereo rendering).

Parameters
focalLengthThe distance to the focal plane from the frustum in world coordinates.

◆ setFOVy()

virtual void Ogre::Frustum::setFOVy ( const Radian fovy)
virtualinherited

Sets the Y-dimension Field Of View (FOV) of the frustum.

Remarks
Field Of View (FOV) is the angle made between the frustum's position, and the edges of the 'screen' onto which the scene is projected. High values (90+ degrees) result in a wide-angle, fish-eye kind of view, low values (30- degrees) in a stretched, telescopic kind of view. Typical values are between 45 and 60 degrees.
This value represents the VERTICAL field-of-view. The horizontal field of view is calculated from this depending on the dimensions of the viewport (they will only be the same if the viewport is square).
Note
Setting the FOV overrides the value supplied for frustum::setNearClipPlane.

◆ setFrustumExtents()

virtual void Ogre::Frustum::setFrustumExtents ( Real  left,
Real  right,
Real  top,
Real  bottom,
FrustrumExtentsType  frustrumExtentsType = FET_PROJ_PLANE_POS 
)
virtualinherited

Manually set the extents of the frustum.

Parameters
left,right,top,bottomThe position where the side clip planes intersect the near clip plane, in eye space OR the tangent of the half angles from the eye to the edges of the near clip plane
frustrumExtentsTypeSpecifies how the extents are represented. Be default they are the positions on near clip plane. However if this is a scene camera it is recommended that you actually use the tangent of the half angles. ie Half the FoV angles. This is because Ogre uses this camera setup to calculate custom clipping planes for PSSM algorithms, and Forward+ algorithms, but alter the near and far clip distances.
If you supply extents as positions on the projection plane the near clip distance has already been calculated as part of the supplied extents, however if they are tangent of the half angles Ogre can apply different near clip distances dynamically.

◆ setFrustumOffset() [1/2]

virtual void Ogre::Frustum::setFrustumOffset ( const Vector2 offset)
virtualinherited

Sets frustum offsets, used in stereo rendering.

Remarks
You can set both horizontal and vertical plane offsets of "eye"; in stereo rendering frustum is moved in horizontal plane. To be able to render from two "eyes" you'll need two cameras rendering on two RenderTargets.
The frustum offsets is in world coordinates, and default to (0, 0) - no offsets.
Parameters
offsetThe horizontal and vertical plane offsets.

◆ setFrustumOffset() [2/2]

virtual void Ogre::Frustum::setFrustumOffset ( Real  horizontal = 0.0,
Real  vertical = 0.0 
)
virtualinherited

Sets frustum offsets, used in stereo rendering.

Remarks
You can set both horizontal and vertical plane offsets of "eye"; in stereo rendering frustum is moved in horizontal plane. To be able to render from two "eyes" you'll need two cameras rendering on two RenderTargets.
The frustum offsets is in world coordinates, and default to (0, 0) - no offsets.
Parameters
horizontalThe horizontal plane offset.
verticalThe vertical plane offset.

◆ setLightCullingVisibility()

void Ogre::Camera::setLightCullingVisibility ( bool  collectLights,
bool  isCubemap 
)

When a camera is created via SceneManager::createCamera, there are two additional parameters.

Parameters
collectLightsTell Ogre to cull lights against this camera. This requires additional CPU power. If a camera is not going to be used for a long time (or it doesn't need lights, which is what happens with shadow mapping cameras) you want this set to false. Otherwise if you need to render and need lights, enable this setting.
isCubemapUse an alternative algorithm to collect lights in 360° around the camera. This is required if the camera is going to be used in passes where CompositorPassSceneDef::mCameraCubemapReorient = true; Does nothing if collectLights = false

◆ setLightMask()

void Ogre::MovableObject::setLightMask ( uint32  lightMask)
inlineinherited

Set a bitwise mask which will filter the lights affecting this object.

Remarks
This mask will be compared against the mask held against Light to determine if a light should affect a given object. By default, this mask is fully set meaning all lights will affect this object

◆ setListener()

void Ogre::MovableObject::setListener ( Listener listener)
inlineinherited

Sets a listener for this object.

Remarks
Note for size and performance reasons only one listener per object is allowed.

◆ setLocalAabb()

void Ogre::MovableObject::setLocalAabb ( const Aabb  box)
inherited

Sets the local axis-aligned bounding box for this object.

Remarks
This bounding box is in local coordinates.

◆ setLodBias()

void Ogre::Camera::setLodBias ( Real  factor = 1.0)

Sets the level-of-detail factor for this Camera.

Remarks
This method can be used to influence the overall level of detail of the scenes rendered using this camera. Various elements of the scene have level-of-detail reductions to improve rendering speed at distance; this method allows you to hint to those elements that you would like to adjust the level of detail that they would normally use (up or down).
The most common use for this method is to reduce the overall level of detail used for a secondary camera used for sub viewports like rear-view mirrors etc. Note that scene elements are at liberty to ignore this setting if they choose, this is merely a hint.
Parameters
factorThe factor to apply to the usual level of detail calculation. Higher values increase the detail, so 2.0 doubles the normal detail and 0.5 halves it.

◆ setLodCamera()

virtual void Ogre::Camera::setLodCamera ( const Camera lodCam)
virtual

Set a pointer to the camera which should be used to determine LOD settings.

Remarks
Sometimes you don't want the LOD of a render to be based on the camera that's doing the rendering, you want it to be based on a different camera. A good example is when rendering shadow maps, since they will be viewed from the perspective of another camera. Therefore this method lets you associate a different camera instance to use to determine the LOD.
To revert the camera to determining LOD based on itself, call this method with a pointer to itself.

◆ setMaterial()

virtual void Ogre::Renderable::setMaterial ( const MaterialPtr material)
virtualinherited

Sets the given material. Overrides HLMS materials.

Reimplemented in Ogre::v1::SubEntity, Ogre::v1::BillboardSet, and Ogre::v1::SimpleRenderable.

◆ setMaterialName()

void Ogre::Renderable::setMaterialName ( const String name,
const String groupName 
)
inherited

Sets the name of the Material to be used. Prefer using HLMS @See setHlms.

◆ setName()

void Ogre::MovableObject::setName ( const String name)
inlineinherited

Sets a custom name for this node.

Doesn't have to be unique

◆ setNearClipDistance()

virtual void Ogre::Frustum::setNearClipDistance ( Real  nearDist)
virtualinherited

Sets the position of the near clipping plane.

Remarks
The position of the near clipping plane is the distance from the frustums position to the screen on which the world is projected. The near plane distance, combined with the field-of-view and the aspect ratio, determines the size of the viewport through which the world is viewed (in world co-ordinates). Note that this world viewport is different to a screen viewport, which has it's dimensions expressed in pixels. The frustums viewport should have the same aspect ratio as the screen viewport it renders into to avoid distortion.
Parameters
nearDistThe distance to the near clipping plane from the frustum in world coordinates.

◆ setOrientation()

void Ogre::Camera::setOrientation ( const Quaternion q)

Sets the camera's orientation.

◆ setOrientationMode()

void Ogre::Frustum::setOrientationMode ( OrientationMode  orientationMode)
inherited

Set the orientation mode of the frustum.

Default is OR_DEGREE_0

Remarks
Setting the orientation of a frustum is only supported on iOS at this time. An exception is thrown on other platforms.

◆ setOrthoWindow()

virtual void Ogre::Frustum::setOrthoWindow ( Real  w,
Real  h 
)
virtualinherited

Sets the orthographic window settings, for use with orthographic rendering only.

Note
Calling this method will recalculate the aspect ratio, use setOrthoWindowHeight or setOrthoWindowWidth alone if you wish to preserve the aspect ratio but just fit one or other dimension to a particular size.
Parameters
wThe width of the view window in world units.
hThe height of the view window in world units.

◆ setOrthoWindowHeight()

virtual void Ogre::Frustum::setOrthoWindowHeight ( Real  h)
virtualinherited

Sets the orthographic window height, for use with orthographic rendering only.

Note
The width of the window will be calculated from the aspect ratio.
Parameters
hThe height of the view window in world units.

◆ setOrthoWindowWidth()

virtual void Ogre::Frustum::setOrthoWindowWidth ( Real  w)
virtualinherited

Sets the orthographic window width, for use with orthographic rendering only.

Note
The height of the window will be calculated from the aspect ratio.
Parameters
wThe width of the view window in world units.

◆ setPolygonModeOverrideable()

virtual void Ogre::Renderable::setPolygonModeOverrideable ( bool  override)
inlinevirtualinherited

Sets whether this renderable's chosen detail level can be overridden (downgraded) by the camera setting.

Parameters
overridetrue means that a lower camera detail will override this renderables detail level, false means it won't.

◆ setPoseWeight()

void Ogre::Renderable::setPoseWeight ( size_t  index,
float  w 
)
inherited

◆ setPosition() [1/2]

void Ogre::Camera::setPosition ( const Vector3 vec)

Sets the camera's position.

◆ setPosition() [2/2]

void Ogre::Camera::setPosition ( Real  x,
Real  y,
Real  z 
)

Sets the camera's position.

◆ setProjectionType()

virtual void Ogre::Frustum::setProjectionType ( ProjectionType  pt)
virtualinherited

Sets the type of projection to use (orthographic or perspective).

Default is perspective.

Reimplemented in Ogre::PCZCamera.

◆ setQueryFlags()

void Ogre::MovableObject::setQueryFlags ( uint32  flags)
inlineinherited

Sets the query flags for this object.

Remarks
When performing a scene query, this object will be included or excluded according to flags on the object and flags on the query. This is a bitwise value, so only when a bit on these flags is set, will it be included in a query asking for that flag. The meaning of the bits is application-specific.

◆ setRenderingDistance()

void Ogre::MovableObject::setRenderingDistance ( Real  dist)
inlineinherited

Sets the distance at which the object is no longer rendered.

Parameters
distDistance beyond which the object will not be rendered (the default is FLT_MAX, which means objects are always rendered). Values equal or below zero will be ignored, and cause an assertion in debug mode.

◆ setRenderingMinPixelSize()

void Ogre::MovableObject::setRenderingMinPixelSize ( Real  pixelSize)
inlineinherited

Sets the minimum pixel size an object needs to be in both screen axes in order to be rendered.

Note
Camera::setUseMinPixelSize() needs to be called for this parameter to be used.
Parameters
pixelSizeNumber of minimum pixels (the default is 0, which means objects are always rendered).

◆ setRenderQueueGroup()

virtual void Ogre::MovableObject::setRenderQueueGroup ( uint8  queueID)
virtualinherited

Sets the render queue group this entity will be rendered through.

Remarks
Render queues are grouped to allow you to more tightly control the ordering of rendered objects. If you do not call this method, all Entity objects default to the default queue (RenderQueue::getDefaultQueueGroup), which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.
See RenderQueue for more details.
Parameters
queueIDEnumerated value of the queue group to use. See the enum RenderQueueGroupID for what kind of values can be used here.
Valid render queue ids are between 0 & 254 inclusive

Reimplemented in Ogre::ParticleSystem, Ogre::Light, Ogre::InternalCubemapProbe, Ogre::v1::Entity, and Ogre::Decal.

◆ setRenderQueueSubGroup()

void Ogre::Renderable::setRenderQueueSubGroup ( uint8  subGroup)
inlineinherited

Sets the render queue sub group.

Remarks
Within the same RenderQueue ID, you may want to have the renderables to have a specific order (i.e. have a mesh, but the hair submesh with alpha blending needs to be rendered last).
RenderQueue Subgroups are useful for manually sorting objects, just like RenderQueue IDs. However, RenderQueue IDs can also be useful for skipping large number of objects through clever compositing and thus a performance optimization. Subgroups cannot be used for such optimizations.
Parameters
subGroupThe sub group. This value can't exceed OGRE_MAKE_MASK( SubRqIdBits ) @See RenderQueue

◆ setShadowRenderingDistance()

void Ogre::MovableObject::setShadowRenderingDistance ( Real  dist)
inlineinherited

Sets the distance at which the object is no longer casting shadows.

Parameters
distDistance beyond which the object will not cast shadows (the default is FLT_MAX, which means objects are always casting shadows). Values equal or below zero will be ignored, and cause an assertion in debug mode.
Note
ShadowRenderingDistance will be clamped to RenderingDistance value
See also
setRenderingDistance

◆ setStatic()

bool Ogre::MovableObject::setStatic ( bool  bStatic)
inherited

Turns this Node into static or dynamic.

Remarks
Switching between dynamic and static has some overhead and forces to update all static scene when converted to static. So don't do it frequently. Static objects are not updated every frame, only when requested explicitly. Use this feature if you plan to have this object unaltered for a very long times
Note all MovableObjects support switching between static & dynamic after they have been created (eg. InstancedEntity)
Changing this attribute will cause to switch the attribute to our parent node, and as a result, all of its other attached entities. @See Node::setStatic
Returns
True if setStatic made an actual change. False otherwise. Can fail because the object was already static/dynamic, or because switching is not supported

◆ setUseIdentityProjection()

void Ogre::Renderable::setUseIdentityProjection ( bool  useIdentityProjection)
inlineinherited

Sets whether or not to use an 'identity' projection.

Remarks
Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not change this. The default is false.
See also
Renderable::getUseIdentityProjection

◆ setUseIdentityView()

void Ogre::Renderable::setUseIdentityView ( bool  useIdentityView)
inlineinherited

Sets whether or not to use an 'identity' view.

Remarks
Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normal renderables need not change this. The default is false.
See also
Renderable::getUseIdentityView

◆ setUseMinPixelSize()

void Ogre::Camera::setUseMinPixelSize ( bool  enable)
inline

Sets whether to use min display size calculations.

When active, objects that derive from MovableObject whose size on the screen is less then a MovableObject::mMinPixelSize will not be rendered.

◆ setUserAny()

virtual OGRE_DEPRECATED void Ogre::Renderable::setUserAny ( const Any anything)
inlinevirtualinherited
Deprecated:
use UserObjectBindings::setUserAny via getUserObjectBindings() instead.

Sets any kind of user value on this object.

Remarks
This method allows you to associate any user value you like with this Renderable. This can be a pointer back to one of your own classes for instance.

◆ setUseRenderingDistance()

virtual void Ogre::Camera::setUseRenderingDistance ( bool  use)
inlinevirtual

Set whether this camera should use the 'rendering distance' on objects to exclude distant objects from the final image.

The default behaviour is to use it.

Parameters
useTrue to use the rendering distance, false not to.

◆ setVisibilityFlags()

void Ogre::MovableObject::setVisibilityFlags ( uint32  flags)
inlineinherited

Sets the visibility flags for this object.

Remarks
As well as a simple true/false value for visibility (as seen in setVisible), you can also set visibility flags that is applied a binary 'and' with the SceneManager's mask and a compositor node pass. To exclude particular objects from rendering. Changes to reserved visibility flags are ignored (won't take effect).

◆ setVisible()

void Ogre::MovableObject::setVisible ( bool  visible)
inlineinherited

Tells this object whether to be visible or not, if it has a renderable component.

Note
An alternative approach of making an object invisible is to detach it from it's SceneNode, or to remove the SceneNode entirely. Detaching a node means that structurally the scene graph changes. Once this change has taken place, the objects / nodes that have been removed have less overhead to the visibility detection pass than simply making the object invisible, so if you do this and leave the objects out of the tree for a long time, it's faster. However, the act of detaching / reattaching nodes is in itself more expensive than setting an object visibility flag, since in the latter case structural changes are not made. Therefore, small or frequent visibility changes are best done using this method; large or more longer term changes are best done by detaching.

◆ setVrData()

void Ogre::Camera::setVrData ( VrData vrData)

Sets VR data for calculating left & right eyes See OpenVR sample for more info.

Parameters
vrDataPointer to valid VrData This pointer must remain valid while the Camera is using it. We won't free this pointer. It is the developer's responsability to free it once no longer in use. Multiple cameras can share the same VrData pointer. The internal data hold by VrData can be changed withohut having to call setVrData again

◆ setWindow()

virtual void Ogre::Camera::setWindow ( Real  left,
Real  top,
Real  right,
Real  bottom 
)
virtual

Sets the viewing window inside of viewport.

Remarks
This method can be used to set a subset of the viewport as the rendering target.
Parameters
leftRelative to Viewport - 0 corresponds to left edge, 1 - to right edge (default - 0).
topRelative to Viewport - 0 corresponds to top edge, 1 - to bottom edge (default - 0).
rightRelative to Viewport - 0 corresponds to left edge, 1 - to right edge (default - 1).
bottomRelative to Viewport - 0 corresponds to top edge, 1 - to bottom edge (default - 1).

◆ synchroniseBaseSettingsWith()

virtual void Ogre::Camera::synchroniseBaseSettingsWith ( const Camera cam)
virtual

Synchronise core camera settings with another.

Remarks
Copies the position, orientation, clip distances, projection type, FOV, focal length and aspect ratio from another camera. Other settings like query flags, reflection etc are preserved.

◆ updateAllBounds()

static void Ogre::MovableObject::updateAllBounds ( const size_t  numNodes,
ObjectData  t 
)
staticinherited

@See SceneManager::updateAllBounds

Remarks
We don't pass by reference on purpose (avoid implicit aliasing)

◆ yaw()

void Ogre::Camera::yaw ( const Radian angle)

Rotates the camera anticlockwise around it's local y axis.

Small constant used to reduce far plane projection to avoid inaccuracies.

◆ mCustomParameter

uint8 Ogre::Renderable::mCustomParameter
inherited

Only valid when using low level materials.

◆ mGlobalIndex

size_t Ogre::MovableObject::mGlobalIndex
inherited

Index in the vector holding this MO reference (could be our parent node, or a global array tracking all movable objecst to avoid memory leaks).

Used for O(1) removals.

Remarks
It is the parent (or our creator) the one that sets this value, not ourselves. Do NOT modify it manually.

◆ mHlmsGlobalIndex

uint32 Ogre::Renderable::mHlmsGlobalIndex
inherited

Index in the vector holding this Rendrable reference in the HLMS datablock.

Used for O(1) removals.

Remarks
Despite being public, Do NOT modify it manually.

◆ mParentIndex

size_t Ogre::MovableObject::mParentIndex
inherited

Index in the vector holding this MO reference (could be our parent node, or a global array tracking all movable objecst to avoid memory leaks).
