Detailed Description

Implements the uniform shadow mapping algorithm in focused mode.

Remarks

Differs from the default shadow mapping projection in that it focuses the shadow map on the visible areas of the scene. This results in better shadow map texel usage, at the expense of some 'swimming' of the shadow texture on receivers as the basis is constantly being reevaluated.

Note

Original implementation by Matthias Fink matth.nosp@m.ias..nosp@m.fink@.nosp@m.web..nosp@m.de, 2006.

Member Function Documentation

getShadowCamera()

void Ogre::FocusedShadowCameraSetup::getShadowCamera ( const SceneManager *  sm, const Camera *  cam, const Light *  light, Camera *  texCam, size_t  iteration, const Vector2 &  viewportRealSize  ) const

overridevirtual

Returns a uniform shadow camera with a focused view.

Reimplemented from Ogre::DefaultShadowCameraSetup.

Reimplemented in Ogre::PSSMShadowCameraSetup.

getXYPadding()

Real Ogre::FocusedShadowCameraSetup::getXYPadding ( ) const

inline

See FocusedShadowCameraSetup::setXYPadding.

setXYPadding()

void Ogre::FocusedShadowCameraSetup::setXYPadding ( Real  pad )

inline

setXYPadding FocusedShadowCameraSetup tries to make the shadow mapping camera fit the casters as tight as possible to minimize aliasing.

But due to various math issues sometimes it ends up being too tight.

If you experience missing shadows or with gaps/holes you may need to increase the padding.

Most likely you want the reverse. In particular circumstances you want maximum quality thus you want to minimize this padding

Parameters

pad	Value in range [0; inf) Negative values may cause glitches
