Member Function Documentation

virtual MCCOMErr MCCOMAPI I3DExShadowFeature::BeginRenderFrame (  I3DShLightsource *  light  )  [pure virtual]

Called by the shell at the beginning of the rendering of each frame. This fonction can be used to calculate a cache (shadow buffer for instance) Parameters: light  : the light on which the shadow feature is applied Implemented in TBasicShadowFeature.

virtual boolean MCCOMAPI I3DExShadowFeature::CalcShadow (  ShadowIO &  shadowIO, const LightingContext &  lightingContext )  [pure virtual]

Calculate the light reaching a point from a light source Note: This function must be SMP compliant (= reentrant) ! Parameters: shadowIO  : a structure containing all the parameters of this call lightingContext  : info about the point being lit True if a shadow was cast Implemented in TBasicShadowFeature.

virtual MCCOMErr MCCOMAPI I3DExShadowFeature::EndRenderFrame (   )  [pure virtual]

Called by the shell at the end of the rendering of each frame. This fonction can be used to delete caches. Implemented in TBasicShadowFeature.
