◆ 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 Function Documentation

◆ _getCachedFrustumPlanes()

const Plane* Ogre::Frustum::_getCachedFrustumPlanes ( void  ) const
inline

Returns the frustum planes, doesn't check if dirty.

◆ _getCachedWorldSpaceCorners()

const Vector3* Ogre::Frustum::_getCachedWorldSpaceCorners ( void  ) const

LightList* Ogre::MovableObject::_getLightList ( )
inlineinherited

Returns a pointer to the current list of lights for this object.

Remarks
You should not modify this list outside of MovableObject::Listener::objectQueryLights (say if you want to use it to implement this method, and use the pointer as a return value) and for reading it's only accurate as at the last frame.

◆ _getManager()

SceneManager* Ogre::MovableObject::_getManager ( void  ) const
inlineinherited

Get the manager of this object, if any (internal use only)

◆ _getObjectData()

ObjectData& Ogre::MovableObject::_getObjectData ( )
inlineinherited

Returns a direct access to the ObjectData state.

◆ _getParentNodeFullTransform()

const Matrix4& Ogre::MovableObject::_getParentNodeFullTransform ( void  ) const
inherited

Returns the full transformation of the parent sceneNode or the attachingPoint node.

◆ _notifyAttached()

virtual void Ogre::MovableObject::_notifyAttached ( Node parent)
virtualinherited

Internal method called to notify the object that it has been attached to a node.

Reimplemented in Ogre::ParticleSystem, and Ogre::v1::Entity.

Referenced by Ogre::PortalBase::_notifyAttached().

◆ _notifyManager()

void Ogre::MovableObject::_notifyManager ( SceneManager man)
inlineinherited

Notify the object of it's manager (internal use only)

◆ _notifyParentNodeMemoryChanged()

virtual void Ogre::MovableObject::_notifyParentNodeMemoryChanged ( void  )
inlinevirtualinherited

◆ _notifyStaticDirty()

virtual void Ogre::MovableObject::_notifyStaticDirty ( void  ) const
inlinevirtualinherited

Called by SceneManager when it is telling we're a static MovableObject being dirty Don't call this directly.

See also
SceneManager::notifyStaticDirty

◆ _releaseManualHardwareResources()

virtual void Ogre::MovableObject::_releaseManualHardwareResources ( )
inlinevirtualinherited

Notifies the movable object that hardware resources were lost.

Remarks
Called automatically by RenderSystem if hardware resources were lost and can not be restored using some internal mechanism. Among affected resources are nested shadow renderables, ManualObjects, etc.

Reimplemented in Ogre::v1::Rectangle2D, Ogre::ManualObject, Ogre::v1::ManualObject, and Ogre::v1::BillboardSet.

◆ _restoreManualHardwareResources()

virtual void Ogre::MovableObject::_restoreManualHardwareResources ( )
inlinevirtualinherited

Notifies the movable object that hardware resources should be restored.

Remarks
Called automatically by RenderSystem if hardware resources were lost and can not be restored using some internal mechanism. Among affected resources are nested shadow renderables, ManualObjects, etc.

Reimplemented in Ogre::v1::Rectangle2D.

◆ _setHlmsHashes()

virtual void Ogre::Renderable::_setHlmsHashes ( uint32  hash,
uint32  casterHash 
)
virtualinherited

Manually sets the hlms hashes. Don't call this directly.

Reimplemented in Ogre::SubItem.

◆ _setNullDatablock()

virtual void Ogre::Renderable::_setNullDatablock ( void  )
virtualinherited

Sets the datablock to a null pointer.

Use case: If you will be destroying an HlmsDatablock and all Renderables associated by it; it makes no sense to change the Renderable's datablock to a default one, only to be destroyed immediately after (you pay an unnecessary performance price).

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.

virtual

Disables reflection modification previously turned on with enableReflection.

◆ enableCustomNearClipPlane() [1/2]

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

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)
virtual

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.

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)
virtual

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.

◆ enableReflection() [2/2]

virtual void Ogre::Frustum::enableReflection ( const Plane p)
virtual

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

inherited

◆ getNumWorldTransforms()

virtual unsigned short Ogre::Renderable::getNumWorldTransforms ( void  ) const

Remarks
When a renderable uses vertex blending, it uses multiple world matrices instead of a single one. Each vertex sent to the pipeline can reference one or more matrices in this list with given weights.

◆ getProjectionMatrix()

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

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
virtual

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

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);.

Overridden from Renderable.

◆ 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.

◆ 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()

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.

◆ removeQueryFlags()

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

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

◆ removeVisibilityFlags()

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

◆ resetFrustumExtents()

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

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

◆ setAspectRatio()

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

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.

◆ 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.

◆ 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 
)
virtual

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 
)
virtual

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() [1/2]

inlinestaticinherited

Set the default visibility flags for all future MovableObject instances.

◆ setFarClipDistance()

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

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.

◆ setFocalLength()

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

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)
virtual

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 
)
virtual

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)
virtual

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 
)
virtual

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.

◆ 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

Remarks
This bounding box is in local coordinates.

◆ 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

◆ 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)
virtual

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.

◆ setOrientationMode()

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

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 
)
virtual

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)
virtual

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)
virtual

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

Note

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

◆ setProjectionType()

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

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

◆ 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.

◆ 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.

◆ 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)
