Detailed Description

This interface contains extra methods for volume primitives allowing more advanced interaction with the scene. If this interface is implemented, neither GetVolumeDensity nor GetVolumeAttenuation are called.


Member Function Documentation

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

Called at the beginning of a rendering.

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

Called at the end of a rendering.

virtual void MCCOMAPI I3DExNewVolumePrimitive::TraceRay ( const Ray3D ray,
const Ray3D localRay,
const real64 tmin,
const real64 tmax,
TMCColorRGBA inOutColor,
TColorRGBLinearEffect linearEffect,
I3DExRaytracer raytracer,
I3DShInstance instance,
uint32  instanceNb,
boolean  isShadowRay,
boolean  isIndirectRay,
boolean  oldShadowFiltering 
) [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
instanceNb A id in the raytraced grid for the hit instance (can be different with same instance in replicators)
isShadowRay True if the ray is a shadow ray.
isIndirectRay True if the ray has already hit a reflective or semi transparent surface
virtual boolean MCCOMAPI I3DExNewVolumePrimitive::UsesShaders (  )  const [pure virtual]

Returns true if this volume primitive uses the shaders that are applyed to it.
