Member Function Documentation

virtual uint32 MCCOMAPI TBasicShadowFeature::AddRef (   )  [inline, virtual]

Increments the reference count of the object Reimplemented from TBasicRenderFeature.

virtual MCCOMErr MCCOMAPI TBasicShadowFeature::BeginRenderFrame (  I3DShLightsource *  light  )  [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 Implements I3DExShadowFeature.

virtual boolean MCCOMAPI TBasicShadowFeature::CalcShadow (  ShadowIO &  shadowIO, const LightingContext &  lightingContext )  [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 Implements I3DExShadowFeature.

virtual MCCOMErr MCCOMAPI TBasicShadowFeature::EndRenderFrame (   )  [virtual]

Called by the shell at the end of the rendering of each frame. This fonction can be used to delete caches. Implements I3DExShadowFeature.

virtual MCCOMErr MCCOMAPI TBasicShadowFeature::QueryInterface (  const MCIID &  riid, void **  ppvObj )  [virtual]

Check if the object supports a given interface and returns a pointer to that interface if it does. Note that QueryInterface will increment the reference count of the object by one if the interface is found. Parameters: riid  GUID of the interface ppvObj  A pointer to the pointer being returned. Reimplemented from TBasicRenderFeature.
