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

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]
