Detailed Description

Parallel Split Shadow Map (PSSM) shadow camera setup.

Remarks:: A PSSM shadow system uses multiple shadow maps per light and maps each texture into a region of space, progressing away from the camera. As such it is most appropriate for directional light setups. This particular version also uses LiSPSM projection for each split to maximise the quality.

Note:: Because PSSM uses multiple shadow maps per light, you will need to increase the number of shadow textures available (via SceneManager) to match the number of shadow maps required (default is 3 per light).

Matrix4 Ogre::LiSPSMShadowCameraSetup::buildFrustumProjection	(	Real	left,
		Real	right,
		Real	bottom,
		Real	top,
		Real	near,
		Real	far
	)			const `[protected, inherited]`

Builds a frustum matrix.

Remarks:: Builds a standard frustum matrix out of the distance infos of the six frustum clipping planes.

Matrix4 Ogre::FocusedShadowCameraSetup::buildViewMatrix	(	const Vector3 &	pos,
		const Vector3 &	dir,
		const Vector3 &	up
	)			const `[protected, inherited]`

Builds a view matrix.

Remarks:: Builds a standard view matrix out of a given position, direction and up vector.

void Ogre::FocusedShadowCameraSetup::calculateB	(	const SceneManager &	sm,
		const Camera &	cam,
		const Light &	light,
		const AxisAlignedBox &	sceneBB,
		const AxisAlignedBox &	receiverBB,
		PointListBody *	out_bodyB
	)			const `[protected, inherited]`

Calculates the intersection bodyB.

Remarks:: The intersection bodyB consists of the concatenation the cam frustum clipped by the scene bounding box followed by a convex hullification with the light's position and the clipping with the scene bounding box and the light frustum: ((V S) + l) S L (: convex intersection, +: convex hull operation). For directional lights the bodyB is assembled out of the camera frustum clipped by the scene bounding box followed by the extrusion of all available bodyB points towards the negative light direction. The rays are intersected by a maximum bounding box and added to the bodyB points to form the final intersection bodyB point list.

Parameters:

	sm,:	scene manager
	cam,:	currently active camera
	light,:	currently active light
	sceneBB,:	scene bounding box for clipping operations
	receiverAABB,:	bounding information for just the receivers
	out_bodyB,:	final intersection bodyB point list

Matrix4 Ogre::LiSPSMShadowCameraSetup::calculateLiSPSM	(	const Matrix4 &	lightSpace,
		const PointListBody &	bodyB,
		const PointListBody &	bodyLVS,
		const SceneManager &	sm,
		const Camera &	cam,
		const Light &	light
	)			const `[protected, inherited]`

Calculates the LiSPSM projection matrix P.

Remarks:: The LiSPSM projection matrix will be built around the axis aligned bounding box of the intersection body B in light space. The distance between the near plane and the projection center is chosen in such a way (distance is set by the para- meter n) that the perspective error is the same on the near and far plane. In case P equals the identity matrix the algorithm falls back to a uniform shadow mapping matrix.

Parameters:

	lightSpace,:	matrix of the light space transformation
	bodyB,:	intersection body B
	bodyLVS,:	intersection body LVS (relevant space in front of the camera)
	sm,:	scene manager
	cam,:	currently active camera
	light,:	currently active light

void Ogre::FocusedShadowCameraSetup::calculateLVS	(	const SceneManager &	sm,
		const Camera &	cam,
		const Light &	light,
		const AxisAlignedBox &	sceneBB,
		PointListBody *	out_LVS
	)			const `[protected, inherited]`

Calculates the bodyLVS.

Remarks:: Calculates the bodyLVS which consists of the convex intersection operation affecting the light frustum, the view frustum, and the current scene bounding box is used to find suitable positions in the viewer's frustum to build the rotation matrix L_r. This matrix is applied after the projection matrix L_p to avoid an accidental flip of the frustum orientation for views tilted with respect to the shadow map.

Parameters:

	scene,:	holds all potential occluders / receivers as one single bounding box of the currently active scene node
	cam,:	current viewer camera
	light,:	current light
	out_LVS,:	intersection body LVS (world coordinates)

Real Ogre::LiSPSMShadowCameraSetup::calculateNOpt	(	const Matrix4 &	lightSpace,
		const AxisAlignedBox &	bodyBABB_ls,
		const PointListBody &	bodyLVS,
		const Camera &	cam
	)			const `[protected, inherited]`

Calculates the distance between camera position and near clipping plane.

Remarks:: n_opt determines the distance between light space origin (shadow camera position) and the near clipping plane to achieve an optimal perspective foreshortening effect. In this way the texel distribution over the shadow map is controlled.

Formula: d n_opt = --------------- sqrt(z1/z0) - 1

Parameters: d: distance between the near and the far clipping plane z0: located on the near clipping plane of the intersection body b z1: located on the far clipping plane with the same x/y values as z0

Note:: A positive value is applied as the distance between viewer and near clipping plane. In case null is returned uniform shadow mapping will be applied.

Parameters:

	lightSpace,:	matrix of the light space transformation
	bodyBABB_ls,:	bounding box of the transformed (light space) bodyB
	bodyLVS,:	point list of the bodyLVS which describes the scene space which is in front of the light and the camera
	cam,:	currently active camera

Real Ogre::LiSPSMShadowCameraSetup::calculateNOptSimple	(	const PointListBody &	bodyLVS,
		const Camera &	cam
	)			const `[protected, inherited]`

Calculates a simpler version than the one above.

void Ogre::FocusedShadowCameraSetup::calculateShadowMappingMatrix	(	const SceneManager &	sm,
		const Camera &	cam,
		const Light &	light,
		Matrix4 *	out_view,
		Matrix4 *	out_proj,
		Camera *	out_cam
	)			const `[protected, inherited]`

Calculates the standard shadow mapping matrix.

Remarks:: Provides the view and projection matrix for standard shadow mapping.

Note:: You can choose which things you want to have: view matrix and/or projection matrix and/or shadow camera. Passing a NULL value as parameter ignores the generation of this specific value.

Parameters:

	sm,:	scene manager
	cam,:	currently active camera
	light,:	currently active light
	out_view,:	calculated uniform view shadow mapping matrix (may be NULL)
	out_proj,:	calculated uniform projection shadow mapping matrix (may be NULL)
	out_cam,:	calculated uniform shadow camera (may be NULL)

void Ogre::PSSMShadowCameraSetup::calculateSplitPoints	(	size_t	splitCount,
		Real	nearDist,
		Real	farDist,
		Real	lambda = `0.95`
	)

Calculate a new splitting scheme.

Parameters:

	splitCount	The number of splits to use
	nearDist	The near plane to use for the first split
	farDist	The far plane to use for the last split
	lambda	Factor to use to reduce the split size

Vector3 Ogre::LiSPSMShadowCameraSetup::calculateZ0_ls	(	const Matrix4 &	lightSpace,
		const Vector3 &	e,
		Real	bodyB_zMax_ls,
		const Camera &	cam
	)			const `[protected, inherited]`

Calculates the visible point on the near plane for the n_opt calculation.

Remarks:: z0 lies on the parallel plane to the near plane through e and on the near plane of the frustum C (plane z = bodyB_zMax_ls) and on the line x = e.x.

Parameters:

	lightSpace,:	matrix of the light space transformation
	e,:	the LiSPSM parameter e is located near or on the near clipping plane of the LiSPSM frustum C
	bodyB_zMax_ls,:	maximum z-value of the light space bodyB bounding box
	cam,:	currently active camera

virtual Degree Ogre::LiSPSMShadowCameraSetup::getCameraLightDirectionThreshold ( ) const [virtual, inherited]

Sets the threshold between the camera and the light direction below which the LiSPSM projection is 'flattened', since coincident light and camera projections cause problems with the perspective skew.

Vector3 Ogre::FocusedShadowCameraSetup::getLSProjViewDir	(	const Matrix4 &	lightSpace,
		const Camera &	cam,
		const PointListBody &	bodyLVS
	)			const `[protected, inherited]`

Returns the projection view direction.

Remarks:: After the matrix L_p is applied the orientation of the light space may tilt for non-identity projections. To prevent a false shadow cast the real view direction is evaluated and applied to the light matrix L.

Parameters:

	lightSpace,:	matrix of the light space transformation
	cam,:	current viewer camera
	bodyLVS,:	intersection body LVS (relevant space in front of the camera)

Vector3 Ogre::FocusedShadowCameraSetup::getNearCameraPoint_ws	(	const Matrix4 &	viewMatrix,
		const PointListBody &	bodyLVS
	)			const `[protected, inherited]`

Returns a valid near-point seen by the camera.

Remarks:: Returns a point that is situated near the camera by analyzing the bodyLVS that contains all the relevant scene space in front of the light and the camera in a point list array. The view matrix is relevant because the nearest point in front of the camera should be determined.

Parameters:

	viewMatrix,:	view matrix of the current camera
	bodyLVS,:	intersection body LVS (relevant space in front of the camera)

virtual void Ogre::LiSPSMShadowCameraSetup::setCameraLightDirectionThreshold ( Degree angle ) [virtual, inherited]

Sets the threshold between the camera and the light direction below which the LiSPSM projection is 'flattened', since coincident light and camera projections cause problems with the perspective skew.

Remarks:: For example, setting this to 20 degrees will mean that as the difference between the light and camera direction reduces from 20 degrees to 0 degrees, the perspective skew will be proportionately removed.

virtual void Ogre::LiSPSMShadowCameraSetup::setOptimalAdjustFactor ( Real n ) [virtual, inherited]

Adjusts the parameter n to produce optimal shadows.

Remarks:: The smaller the parameter n, the stronger the perspective warping effect. The consequence of a stronger warping is that the near shadows will gain quality while the far ones will lose it. Depending on your scene and light types you may want to tweak this value - for example directional lights tend to benefit from higher values of n than other types of light, especially if you expect to see more distant shadows (say if the viewpoint is higher above the ground plane). Remember that you can supply separate ShadowCameraSetup instances configured differently per light if you wish.

Parameters:

n

The adjustment factor - default is 0.1f.

Definition at line 216 of file OgreShadowCameraSetupLiSPSM.h.

void Ogre::PSSMShadowCameraSetup::setOptimalAdjustFactor	(	size_t	splitIndex,
		Real	factor
	)

Set the LiSPSM optimal adjust factor for a given split (call after configuring splits).

void Ogre::PSSMShadowCameraSetup::setSplitPadding ( Real pad )

Set the padding factor to apply to the near & far distances when matching up splits to one another, to avoid 'cracks'.

Definition at line 98 of file OgreShadowCameraSetupPSSM.h.

void Ogre::PSSMShadowCameraSetup::setSplitPoints ( const SplitPointList & newSplitPoints )

Manually configure a new splitting scheme.

Parameters:

newSplitPoints

A list which is splitCount + 1 entries long, containing the split points. The first value is the near point, the last value is the far point, and each value in between is both a far point of the previous split, and a near point for the next one.

void Ogre::FocusedShadowCameraSetup::setUseAggressiveFocusRegion ( bool aggressive ) [inherited]

Sets whether or not to use the more aggressive approach to deciding on the focus region or not.

Note:: There are 2 approaches that can be used to define the focus region, the more aggressive way introduced by Wimmer et al, or the original way as described in Stamminger et al. Wimmer et al's way tends to come up with a tighter focus region but in rare cases (mostly highly glancing angles) can cause some shadow casters to be clipped incorrectly. By default the more aggressive approach is used since it leads to significantly better results in most cases, but if you experience clipping issues, you can use the less aggressive version.

Parameters:

aggressive

True to use the more aggressive approach, false otherwise.

Definition at line 278 of file OgreShadowCameraSetupFocused.h.

virtual void Ogre::LiSPSMShadowCameraSetup::setUseSimpleOptimalAdjust ( bool s ) [virtual, inherited]

Sets whether or not to use a slightly simpler version of the camera near point derivation (default is true).

Definition at line 224 of file OgreShadowCameraSetupLiSPSM.h.

Matrix4 Ogre::FocusedShadowCameraSetup::transformToUnitCube	(	const Matrix4 &	m,
		const PointListBody &	body
	)			const `[protected, inherited]`

Transforms a given body to the unit cube (-1,-1,-1) / (+1,+1,+1) with a specific shadow matrix enabled.

Remarks:: Transforms a given point list body object with the matrix m and then maps its extends to a (-1,-1,-1) / (+1,+1,+1) unit cube

Parameters:

	m,:	transformation matrix applied on the point list body
	body,:	contains the points of the extends of all valid scene elements which are mapped to the unit cube
