void osgShadow::ShadowSettings::setDebugDraw ( bool  debugDraw)
inline
void osgShadow::ShadowSettings::setLightNum ( int  lightNum)
inline

Set the LightNum of the light in the scene to assign a shadow for. Default value is -1, which signifies that shadow technique should automatically select an active light to assign a shadow, typically this will be the first active light found.

void osgShadow::ShadowSettings::setNumShadowMapsPerLight ( unsigned int  numShadowMaps)
inline
void osgShadow::ShadowSettings::setPerspectiveShadowMapCutOffAngle ( double  angle)
inline

Set the cut off angle, in degrees, between the light direction and the view direction that determines whether perspective shadow mapping is appropriate, or thar orthographic shadow map should be used instead. Default is 2 degrees so that for any angle greater than 2 degrees perspective shadow map will be used, and any angle less than 2 degrees orthographic shadow map will be used. Note, if ShadowMapProjectionHint is set to ORTHOGRAPHIC_SHADOW_MAP then an orthographic shadow map will always be used.

void osgShadow::ShadowSettings::setTextureSize ( const osg::Vec2s textureSize)
inline

Set the size of the shadow map textures.

void osgShadow::ShadowSettings::setUseOverrideForShadowMapTexture ( bool  useOverride)
inline

Set whether to use osg::StateAttribute::OVERRIDE for the shadow map texture. Enabling override will force the shadow map texture to override any texture set on the shadow maps texture unit.
