Definition: OgrePlatform.h:260
A viewpoint from which the scene will be rendered.
Definition: OgreCamera.h:87
Implements the Light Space Perspective Shadow Mapping Algorithm.
Representation of a dynamic light source in the scene.
Definition: OgreLight.h:74
Parallel Split Shadow Map (PSSM) shadow camera setup.
virtual void getShadowCamera(const Ogre::SceneManager *sm, const Ogre::Camera *cam, const Ogre::Viewport *vp, const Ogre::Light *light, Ogre::Camera *texCam, size_t iteration) const
Returns a LiSPSM shadow camera with PSSM splits base on iteration.
void calculateSplitPoints(uint splitCount, Real nearDist, Real farDist, Real lambda=0.95)
Calculate a new splitting scheme.
void setOptimalAdjustFactor(size_t splitIndex, Real factor)
Set the LiSPSM optimal adjust factor for a given split (call after configuring splits).
void setSplitPadding(Real pad)
Set the padding factor to apply to the near & far distances when matching up splits to one another,...
Real getOptimalAdjustFactor() const
Overridden, recommended internal use only since depends on current iteration.
vector< Real >::type OptimalAdjustFactorList
Real getOptimalAdjustFactor(size_t splitIndex) const
Returns the optimal adjust factor for a given split.
const SplitPointList & getSplitPoints() const
Returns the calculated split points.
void setSplitPoints(const SplitPointList &newSplitPoints)
Manually configure a new splitting scheme.
Real getSplitPadding() const
Get the padding factor to apply to the near & far distances when matching up splits to one another,...
PSSMShadowCameraSetup()
Constructor, defaults to 3 splits.
uint getSplitCount() const
Get the number of splits.
