Detailed Description

Manages single shadow split parameters and shadow casters. Spot lights always have one split. Directions lights have one split per cascade. Point lights always have six splits.

GetLightProcessor()

LightProcessor * Urho3D::ShadowSplitProcessor::GetLightProcessor ( ) const

inline

Return immutable

GetShadowCasters()

(

float

subPixelOffset

)

const

Return values are valid after shadow map is finalized
