virtual void MCCOMAPI I3DExNewVolumePrimitive::BeginRender (   )  [pure virtual]

Called at the beginning of a rendering. (Not called yet)

Called at the end of a rendering. (Not called yet)

virtual void MCCOMAPI I3DExNewVolumePrimitive::TraceRay (  const Ray3D &  ray, const Ray3D &  localRay, real64  tmin, real64  tmax, TMCColorRGBA &  inOutColor, I3DExRaytracer *  raytracer, I3DShInstance *  instance, boolean  isShadowRay, boolean  isIndirectRay )  [pure virtual]

Filter a ray by a volume primitive. Parameters: ray  The ray in global coordinates localRay  The ray in local coordinates tmin  The beginning of the segment tmax  The end of the segment inOutColor  On input, the color of the point behind the ray. On ouput the color of the light once filtered through the volume raytracer  A pointer to the raytracer used for the lighting instance  The instance of the volume primitive isShadowRay  True if the ray is a shadow ray.
