calculateSplitPoints()

void SO3::StableCSMShadowCameraSetup::calculateSplitPoints	(	size_t	cascadeCount,
		Ogre::Real	firstSplitDist,
		Ogre::Real	farDist,
		Ogre::Real	lambda = 0.95
	)

Calculate a new splitting scheme.

Parameters

cascadeCount	The number of cascades to use
firstSplitDist	distance of the first split
farDist	The far plane to use for the last split
lambda	Value between 0 (linear splits) and 1 (logarithmic splits)

Definition at line 397 of file SO3ShadowCSM.cpp.

getCascadeCount()

size_t SO3::StableCSMShadowCameraSetup::getCascadeCount ( ) const

inline

Get the number of splits.

Definition at line 103 of file SO3ShadowCSM.h.

getShadowCamera()

void SO3::StableCSMShadowCameraSetup::getShadowCamera ( const Ogre::SceneManager *  sm, const Ogre::Camera *  cam, const Ogre::Viewport *  vp, const Ogre::Light *  light, Ogre::Camera *  texCam, size_t  iteration  ) const

virtual

Returns a stable CSM shadow camera for the given iteration.

Definition at line 428 of file SO3ShadowCSM.cpp.

getShadowCameraForCascade()

void SO3::StableCSMShadowCameraSetup::getShadowCameraForCascade ( const Ogre::SceneManager *  sm, const Ogre::Camera *  cam, const Ogre::Viewport *  vp, const Ogre::Light *  light, Ogre::Camera *  texCam, size_t  iteration, Ogre::Real  nearSplit, Ogre::Real  farSplit  ) const

protected

Definition at line 452 of file SO3ShadowCSM.cpp.

getSplitPadding()

Ogre::Real SO3::StableCSMShadowCameraSetup::getSplitPadding ( ) const

inline

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

Definition at line 101 of file SO3ShadowCSM.h.

getSplitPoints()

const SplitPointList & SO3::StableCSMShadowCameraSetup::getSplitPoints ( ) const

inline

Returns the calculated split points.

Definition at line 110 of file SO3ShadowCSM.h.

setSplitPadding()

void SO3::StableCSMShadowCameraSetup::setSplitPadding ( Ogre::Real  pad )

inline

Definition at line 96 of file SO3ShadowCSM.h.

setSplitPoints()

void SO3::StableCSMShadowCameraSetup::setSplitPoints

(

const SplitPointList &

newSplitPoints

)

Manually configure a new splitting scheme.

Parameters

newSplitPoints

A list which is cascadeCount + 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.
