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

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.

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. 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.

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.

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).

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.

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.

virtual void Ogre::ShadowCaster::extrudeBounds	(	AxisAlignedBox &	box,
		const Vector4 &	lightPos,
		Real	extrudeDist
	)			const [protected, virtual, inherited]

Utility method for extruding a bounding box.

Parameters:

	box	Original bounding box, will be updated in-place
	lightPos	4D light position in object space, when w=0.0f this represents a directional light
	extrudeDist	The distance to extrude

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

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

virtual void Ogre::ShadowCaster::generateShadowVolume	(	EdgeData *	edgeData,
		const HardwareIndexBufferSharedPtr &	indexBuffer,
		const Light *	light,
		ShadowRenderableList &	shadowRenderables,
		unsigned long	flags
	)			[protected, virtual, inherited]

Generates the indexes required to render a shadow volume into the index buffer which is passed in, and updates shadow renderables to use it.

Parameters:

	edgeData	The edge information to use
	indexBuffer	The buffer into which to write data into; current contents are assumed to be discardable.
	light	The light, mainly for type info as silhouette calculations should already have been done in updateEdgeListLightFacing
	shadowRenderables	A list of shadow renderables which has already been constructed but will need populating with details of the index ranges to be used.
	flags	Additional controller flags, see ShadowRenderableFlags

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.

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.

virtual const Matrix4& Ogre::Frustum::getProjectionMatrixRS

(

void

)

const [virtual]

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.

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.

bool Ogre::Renderable::getUseIdentityProjection

(

void

)

const [inherited]

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.

Remarks:

Usually Renderable objects will use a view matrix as determined by the active camera.

virtual void Ogre::Renderable::postRender	(	SceneManager *	sm,

Called immediately after the Renderable has been rendered.

Definition at line 127 of file OgreRenderable.h.

virtual bool Ogre::Renderable::preRender	(	SceneManager *	sm,
		RenderSystem *	rsys
	)			[virtual, inherited]

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.

Parameters:

	sphere	The world-space sphere to project
	radius	Radius of the sphere
	left,top,right,bottom	Pointers to destination values, these will be completed with the normalised device coordinates (in the range {-1,1})

Returns:

true if the sphere was projected to a subset of the near plane, false if the entire near plane was contained

Reimplemented in Ogre::Camera.

virtual const LightList& Ogre::MovableObject::queryLights

(

void

)

const [virtual, 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.

void Ogre::Renderable::removeCustomParameter

virtual void Ogre::Frustum::resetFrustumExtents

(

)

[virtual]

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

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.

void Ogre::MovableObject::setCastShadows

(

bool

enabled

)

[inherited]

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.

Definition at line 518 of file OgreMovableObject.h.

void Ogre::Renderable::setCustomParameter	(	size_t	index,
		const Vector4 &	value
	)			[inherited]

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.

Definition at line 240 of file OgreRenderable.h.

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

See also:

Frustum::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:

	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.

Frustum::setCustomProjectionMatrix, Matrix4::isAffine

virtual void Ogre::MovableObject::setDebugDisplayEnabled

(

bool

enabled

)

[virtual, inherited]

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.

Definition at line 434 of file OgreMovableObject.h.

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:

far

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.

virtual void Ogre::Frustum::setFocalLength

(

Real

focalLength = 1.0

)

[virtual]

Sets frustum focal length (used in stereo rendering).

Parameters:

focalLength

The distance to the focal plane from the frustum in world coordinates.

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.

virtual void Ogre::Frustum::setFrustumExtents	(	Real	left,
		Real	right,
		Real	top,
		Real	bottom
	)			[virtual]

Manually set the extents of the frustum.

Parameters:

left,right,top,bottom

The position where the side clip planes intersect the near clip plane, in eye space

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:

	horizontal	The horizontal plane offset.
	vertical	The vertical plane offset.

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:

offset

The horizontal and vertical plane offsets.

virtual void Ogre::MovableObject::setLightMask

(

uint32

lightMask

)

[virtual, 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

virtual void Ogre::MovableObject::setListener

(

Listener *

listener

)

[virtual, inherited]

Sets a listener for this object.

Remarks:

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

Definition at line 445 of file OgreMovableObject.h.

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:

near

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

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.

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:

w,h

The dimensions of the view window in world units

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:

h

The height of the view window in world units

virtual void Ogre::Frustum::setOrthoWindowWidth

(

Real

w

)

[virtual]

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:

w

The width of the view window in world units

virtual void Ogre::Renderable::setPolygonModeOverrideable

(

bool

override

)

[virtual, inherited]

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.

Definition at line 323 of file OgreRenderable.h.

virtual void Ogre::Frustum::setProjectionType

(

ProjectionType

pt

)

[virtual]

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

Default is perspective.

virtual void Ogre::MovableObject::setQueryFlags

(

uint32

flags

)

[virtual, inherited]

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.

Definition at line 391 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setRenderingDistance

(

Real

dist

)

[virtual, inherited]

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

Note:

Camera::setUseRenderingDistance() needs to be called for this parameter to be used.

Parameters:

dist

Distance beyond which the object will not be rendered (the default is 0, which means objects are always rendered).

Definition at line 298 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setRenderingMinPixelSize

(

Real

pixelSize

)

[virtual, inherited]

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).

Definition at line 311 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setRenderQueueGroup

(

uint8

queueID

)

[virtual, inherited]

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::Entity, and Ogre::ParticleSystem.

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

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::Entity.

virtual void Ogre::Renderable::setRenderSystemData

Definition at line 406 of file OgreRenderable.h.

void Ogre::Renderable::setUseIdentityProjection

(

bool

useIdentityProjection

)

[inherited]

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

Definition at line 163 of file OgreRenderable.h.

void Ogre::Renderable::setUseIdentityView

(

bool

useIdentityView

)

[inherited]

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.

)

[virtual, inherited]

Deprecated:

virtual void Ogre::MovableObject::setUserAny

(

Definition at line 328 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setVisibilityFlags

(

uint32

flags

)

[virtual, inherited]

Sets the visiblity flags for this object.

Remarks:

As well as a simple true/false value for visibility (as seen in setVisible), you can also set visiblity flags which when 'and'ed with the SceneManager's visibility mask can also make an object invisible.

Definition at line 419 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setVisible

(

bool

visible

)

[virtual, inherited]

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.

Reimplemented in Ogre::Light.

virtual void Ogre::ShadowCaster::updateEdgeListLightFacing	(	EdgeData *	edgeData,
		const Vector4 &	lightPos
	)			[protected, virtual, inherited]

Tells the caster to perform the tasks necessary to update the edge data's light listing.

Can be overridden if the subclass needs to do additional things.

void Ogre::Frustum::visitRenderables	(	Renderable::Visitor *	visitor,
		bool	debugRenderables = false
	)			[virtual]

Method to allow a caller to abstractly iterate over the Renderable instances that this MovableObject will add to the render queue when asked, if any.

Parameters:

	visitor	Pointer to a class implementing the Renderable::Visitor interface which will be called back for each Renderable which will be queued. Bear in mind that the state of the Renderable instances may not be finalised depending on when you call this.
	debugRenderables	If false, only regular renderables will be visited (those for normal display). If true, debug renderables will be included too.

Implements Ogre::MovableObject.
