	)

inherited

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

useFixed	If `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.
fixedAxis	The axis to use if the first parameter is true.

◆ setAutoTracking()

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

inherited

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

enabled	If 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.
target	Pointer 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.
offset	If 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.

Deprecated:: attach to SceneNode and use SceneNode::setAutoTracking

◆ setLodBias()

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

inherited

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

factor The 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.

◆ getLodBias()

Real Ogre::Camera::getLodBias ( void ) const

inherited

Returns the level-of-detail bias factor currently applied to this camera.

Remarks: See Camera::setLodBias for more details.

◆ setLodCamera()

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

virtualinherited

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.

◆ getLodCamera()

virtual const Camera* Ogre::Camera::getLodCamera ( ) const

virtualinherited

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

Remarks: If setLodCamera hasn't been called with a different camera, this method will return 'this'.

inherited

Retrieves if AutoAspectRatio is currently set or not.

◆ setCullingFrustum()

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

inlineinherited

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.

See also: Camera::setUseMinDisplaySize

◆ getPixelDisplayRatio()

Real Ogre::Camera::getPixelDisplayRatio ( ) const

inlineinherited

Returns an estimated ratio between a pixel and the display area it represents.

For orthographic cameras this function returns the amount of meters covered by a single pixel along the vertical axis. For perspective cameras the value returned is the amount of meters covered by a single pixel per meter distance from the camera.

Note: This parameter is calculated just before the camera is rendered; This parameter is used in min display size calculations.

◆ setFOVy()

void Ogre::Frustum::setFOVy ( const Radian & fovy )

inherited

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.

◆ getFOVy()

const Radian& Ogre::Frustum::getFOVy ( void ) const

inherited

Retrieves the frustums Y-dimension Field Of View (FOV).

◆ setNearClipDistance()

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

inherited

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

nearDist The distance to the near clipping plane from the frustum in world coordinates.

◆ setFarClipDistance()

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

inherited

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

farDist The 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.

◆ setAspectRatio()

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

inherited

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.

◆ getAspectRatio()

inherited

Retrieves the current aspect ratio.

◆ setFrustumOffset() [1/2]

void Ogre::Frustum::setFrustumOffset ( const Vector2 & offset )

inherited

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.

void Ogre::Frustum::getFrustumExtents	(	Real &	outleft,
		Real &	outright,
		Real &	outtop,
		Real &	outbottom
	)		const

inherited

Deprecated:

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ getProjectionMatrixRS()

const Matrix4& Ogre::Frustum::getProjectionMatrixRS ( void ) const

inherited

Gets the projection matrix for this frustum adjusted for the current rendersystem specifics (may be right or left-handed, depth range may vary).

Remarks: This method retrieves the rendering-API dependent version of the projection matrix. If you want a 'typical' projection matrix then use getProjectionMatrix.

◆ getProjectionMatrixWithRSDepth()

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

inherited

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.

◆ getProjectionMatrix()

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

inherited

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.

◆ calcViewMatrixRelative()

void Ogre::Frustum::calcViewMatrixRelative	(	const Vector3 &	relPos,
		Matrix4 &	matToUpdate
	)		const

inherited

Calculate a view matrix for this frustum, relative to a potentially dynamic point.

Mainly for use by OGRE internally when using camera-relative rendering for frustums that are not the centre (e.g. texture projection)

◆ setCustomViewMatrix()

void Ogre::Frustum::setCustomViewMatrix	(	bool	enable,
		const Matrix4 &	viewMatrix = `Matrix4::IDENTITY`
	)

inherited

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

enable	If `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.
viewMatrix	The custom view matrix to use, the matrix must be an affine matrix.

◆ setCustomProjectionMatrix()

void Ogre::Frustum::setCustomProjectionMatrix	(	bool	enable,
		const Matrix4 &	projectionMatrix = `Matrix4::IDENTITY`
	)

inherited

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 it's position and orientation.

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.

Parameters

enable	If `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.
projectionMatrix	The custom view matrix to use.

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

◆ enableReflection() [1/2]

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

inherited

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

Remarks: This is obviously useful for performing planar reflections.

◆ enableReflection() [2/2]

void Ogre::Frustum::enableReflection ( const MovablePlane * p )

inherited

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.

◆ disableReflection()

void Ogre::Frustum::disableReflection ( void )

inherited

Disables reflection modification previously turned on with enableReflection.

◆ isReflected()

◆ enableCustomNearClipPlane() [1/2]

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

inherited

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

plane The 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]

void Ogre::Frustum::enableCustomNearClipPlane ( const Plane & plane )

inherited

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.

inlineinherited

Returns the name of this object.

◆ getParentNode()

Node* Ogre::MovableObject::getParentNode ( void ) const

inlineinherited

Returns the node to which this object is attached.

Remarks: A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. Both are Node subclasses so this method will return either.

◆ getParentSceneNode()

SceneNode* Ogre::MovableObject::getParentSceneNode ( void ) const

inherited

Returns the scene node to which this object is attached.

Remarks: A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. This method will return the scene node of the parent entity if the latter is true.

Reimplemented in Ogre::Entity, and Ogre::PortalBase.

◆ 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.

Referenced by Ogre::Light::setVisible().

◆ getVisible()

bool Ogre::MovableObject::getVisible ( void ) const

inlineinherited

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

Remarks: Returns the value set by MovableObject::setVisible only.

◆ getRenderingDistance()

Real Ogre::MovableObject::getRenderingDistance ( void ) const

inlineinherited

Gets the distance at which batches are no longer rendered.

◆ 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

pixelSize Number of minimum pixels (the default is 0, which means objects are always rendered).

◆ getRenderingMinPixelSize()

Real Ogre::MovableObject::getRenderingMinPixelSize ( ) const

inlineinherited

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

See also: UserObjectBindings::setUserAny.

◆ 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

queueID Enumerated value of the queue group to use. See the enum RenderQueueGroupID for what kind of values can be used here.

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

◆ setRenderQueueGroupAndPriority()

virtual void Ogre::MovableObject::setRenderQueueGroupAndPriority	(	uint8	queueID,
		ushort	priority
	)

virtualinherited

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

Remarks: Render queues are grouped to allow you to more tightly control the ordering of rendered objects. Within a single render group there another type of grouping called priority which allows further control. If you do not call this method, all Entity objects default to the default queue and priority (RenderQueue::getDefaultQueueGroup, RenderQueue::getDefaultRenderablePriority), 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

queueID	Enumerated value of the queue group to use. See the enum RenderQueueGroupID for what kind of values can be used here.
priority	The priority within a group to use.

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

◆ getRenderQueueGroup()

Reimplemented in Ogre::InstancedEntity.

◆ 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.

◆ addQueryFlags()

void Ogre::MovableObject::addQueryFlags ( uint32 flags )

inlineinherited

As setQueryFlags, except the flags passed as parameters are appended to the existing flags on this object.

◆ 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.

◆ getQueryFlags()

uint32 Ogre::MovableObject::getQueryFlags ( void ) const

inlineinherited

Returns the query flags relevant for this object.

◆ setDefaultQueryFlags()

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

inlinestaticinherited

Get the default query flags for all future MovableObject instances.

◆ 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 which when 'and'ed with the SceneManager's visibility mask can also make an object invisible.

◆ addVisibilityFlags()

void Ogre::MovableObject::addVisibilityFlags ( uint32 flags )

inlineinherited

As setVisibilityFlags, except the flags passed as parameters are appended to the existing flags on this object.

◆ removeVisibilityFlags()

inlinestaticinherited

Get the default visibility flags for all future MovableObject instances.

◆ 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.

◆ getListener()

Listener* Ogre::MovableObject::getListener ( void ) const

inlineinherited

Gets the current listener for this object.

◆ queryLights()

const LightList& Ogre::MovableObject::queryLights ( void ) const

inherited

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

Remarks: By default, this method gives the listener a chance to populate light list first, if there is no listener or Listener::objectQueryLights returns NULL, it'll query the light list from parent entity if it is present, or returns SceneNode::findLights if it has parent scene node, otherwise it just returns an empty list.

: The object internally caches the light list, so it will recalculate it only when object is moved, or lights that affect the frustum have been changed (

See also: SceneManager::_getLightsDirtyCounter), but if listener exists, it will be called each time, so the listener should implement their own cache mechanism to optimise performance.

: This method can be useful when implementing Renderable::getLights in case the renderable is a part of the movable.

Returns: The list of lights use to lighting this object.

◆ getLightMask()

uint32 Ogre::MovableObject::getLightMask ( ) const

inlineinherited

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

Remarks: By default, this mask is fully set meaning all lights will affect this object

◆ setLightMask()

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

inherited

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

◆ _getLightList()

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.

◆ getEdgeList()

EdgeData* Ogre::MovableObject::getEdgeList ( void )

inlinevirtualinherited

Returns details of the edges which might be used to determine a silhouette.

Implements Ogre::ShadowCaster.

Reimplemented in Ogre::StaticGeometry::Region.

◆ hasEdgeList()

bool Ogre::MovableObject::hasEdgeList ( void )

Implements Ogre::ShadowCaster.

Reimplemented in Ogre::StaticGeometry::Region.

◆ getShadowVolumeRenderableIterator()

		HardwareIndexBufferSharedPtr *	indexBuffer,
		size_t *	indexBufferUsedSize,
		bool	extrudeVertices,
		Real	extrusionDist,
		unsigned long	flags = `0`
	)

const AxisAlignedBox& Ogre::MovableObject::getDarkCapBounds	(	const Light &	light,
		Real	dirLightExtrusionDist
	)		const

virtualinherited

Overridden member from ShadowCaster.

Implements Ogre::ShadowCaster.

◆ 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.

◆ getCastShadows()

bool Ogre::MovableObject::getCastShadows ( void ) const

inlinevirtualinherited

Returns whether shadow casting is enabled for this object.

Implements Ogre::ShadowCaster.

◆ getReceivesShadows()

bool Ogre::MovableObject::getReceivesShadows ( )

inherited

Returns whether the Material of any Renderable that this MovableObject will add to the render queue will receive shadows.

◆ getPointExtrusionDistance()

Real Ogre::MovableObject::getPointExtrusionDistance ( const Light * l ) const

virtualinherited

Get the distance to extrude for a point/spot light.

Implements Ogre::ShadowCaster.

◆ setDebugDisplayEnabled()

void Ogre::MovableObject::setDebugDisplayEnabled ( bool enabled )

inlineinherited

Sets whether or not the debug display of this object is enabled.

Remarks: Some objects aren't visible themselves but it can be useful to display a debug representation of them. Or, objects may have an additional debug display on top of their regular display. This option enables / disables that debug display. Objects that are not visible never display debug geometry regardless of this setting.

◆ isDebugDisplayEnabled()

bool Ogre::MovableObject::isDebugDisplayEnabled ( void ) const

inlineinherited

Gets whether debug display of this object is enabled.

◆ clearShadowRenderableList()

static void Ogre::ShadowCaster::clearShadowRenderableList ( ShadowRenderableList & shadowRenderables )

staticinherited

Common implementation of releasing shadow renderables.

◆ extrudeVertices()

static void Ogre::ShadowCaster::extrudeVertices	(	const HardwareVertexBufferSharedPtr &	vertexBuffer,
		size_t	originalVertexCount,
		const Vector4 &	lightPos,
		Real	extrudeDist
	)

staticinherited

Utility method for extruding vertices based on a light.

Remarks: Unfortunately, because D3D cannot handle homogeneous (4D) position coordinates in the fixed-function pipeline (GL can, but we have to be cross-API), when we extrude in software we cannot extrude to infinity the way we do in the vertex program (by setting w to 0.0f). Therefore we extrude by a fixed distance, which may cause some problems with larger scenes. Luckily better hardware (ie vertex programs) can fix this.

Parameters

vertexBuffer	The vertex buffer containing ONLY xyz position values, which must be originalVertexCount * 2 * 3 floats long.
originalVertexCount	The count of the original number of vertices, i.e. the number in the mesh, not counting the doubling which has already been done (by VertexData::prepareForShadowVolume) to provide the extruded area of the buffer.
lightPos	4D light position in object space, when w=0.0f this represents a directional light.
extrudeDist	The distance to extrude.

◆ getAnimableValueNames()

const StringVector& Ogre::AnimableObject::getAnimableValueNames ( void ) const

inlineinherited

Gets a list of animable value names for this object.

References Ogre::Exception::ERR_ITEM_NOT_FOUND, and OGRE_EXCEPT.

◆ createAnimableValue()

virtual AnimableValuePtr Ogre::AnimableObject::createAnimableValue ( const String & valueName )

inlinevirtualinherited

Create a reference-counted AnimableValuePtr for the named value.

Remarks: You can use the returned object to animate a value on this object, using AnimationTrack. Subclasses must override this if they wish to support animation of their values.

Reimplemented in Ogre::Light.

References Ogre::Exception::ERR_ITEM_NOT_FOUND, and OGRE_EXCEPT.

◆ getTechnique()

virtual Technique* Ogre::Renderable::getTechnique ( void ) const

inlinevirtualinherited

Retrieves a pointer to the Material Technique this renderable object uses.

Remarks: This is to allow Renderables to use a chosen Technique if they wish, otherwise they will use the best Technique available for the Material they are using.

Reimplemented in Ogre::InstanceBatch, Ogre::InstancedGeometry::GeometryBucket, Ogre::StaticGeometry::GeometryBucket, and Ogre::SubEntity.

◆ 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::BillboardChain.

◆ postRender()

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

inlinevirtualinherited

Called immediately after the Renderable has been rendered.

◆ getNumWorldTransforms()

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

inlinevirtualinherited

Returns the number of world transform matrices this renderable requires.

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. If a renderable does not use vertex blending this method returns 1, which is the default for simplicity.

Reimplemented in Ogre::BorderRenderable, Ogre::SubEntity, Ogre::InstancedGeometry::GeometryBucket, Ogre::BaseInstanceBatchVTF, Ogre::InstanceBatchHW, and Ogre::InstanceBatchShader.

◆ 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

◆ 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

◆ 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

◆ 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

◆ getCastsShadows()

virtual bool Ogre::Renderable::getCastsShadows ( void ) const

inlinevirtualinherited

Method which reports whether this renderable would normally cast a shadow.

Remarks: Subclasses should override this if they could have been used to generate a shadow.

Reimplemented in Ogre::SubEntity, Ogre::InstancedGeometry::GeometryBucket, and Ogre::StaticGeometry::GeometryBucket.

◆ 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

index	The 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.
value	The value to associate.

◆ removeCustomParameter()

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

inlineinherited

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

Parameters

index Index of the parameter to remove.

See also: setCustomParameter for full details.

◆ hasCustomParameter()

bool Ogre::Renderable::hasCustomParameter ( size_t index ) const

inlineinherited

Checks whether a custom value is associated with this Renderable at the given index.

Parameters

index Index of the parameter to check for existence.

See also: setCustomParameter for full details.

◆ getCustomParameter()

const Vector4& Ogre::Renderable::getCustomParameter ( size_t index ) const

inlineinherited

Gets the custom value associated with this Renderable at the given index.

Parameters

index Index of the parameter to retrieve.

See also: setCustomParameter for full details.

References Ogre::Exception::ERR_ITEM_NOT_FOUND, and OGRE_EXCEPT.

◆ _updateCustomGpuParameter()

virtual void Ogre::Renderable::_updateCustomGpuParameter	(	const GpuProgramParameters::AutoConstantEntry &	constantEntry,
		GpuProgramParameters *	params
	)		const

inlinevirtualinherited

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

constantEntry	The auto constant entry referring to the parameter being updated
params	The parameters object which this method should call to set the updated parameters.

Reimplemented in Ogre::SubEntity.

◆ setPolygonModeOverrideable()

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

inlineinherited

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

Parameters

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

◆ getPolygonModeOverrideable()

bool Ogre::Renderable::getPolygonModeOverrideable ( void ) const

inlineinherited

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

Referenced by Ogre::BorderRenderable::getPolygonModeOverrideable().
