virtual boolean MCCOMAPI RayHit (RayHitParameters &params)=0
virtual MCCOMErr MCCOMAPI IsInfiniteBB (boolean &isInfinite)=0

Detailed Description

In addition to describing geometry a geometric primitive can define a custom ray-tracing routine rather than relying only on facets or patches. This is done by inheriting from IRaytracablePrimitive in addition to I3DExGeometricPrimitive (or TBasicPrimitive).


Member Function Documentation

virtual MCCOMErr MCCOMAPI IRaytracablePrimitive::IsInfiniteBB ( boolean isInfinite  )  [pure virtual]

Sets a boolean to true if the object is infinite.

Parameters:
isInfinite True on exit if the bounding box is infinite.
virtual boolean MCCOMAPI IRaytracablePrimitive::RayHit ( RayHitParameters params  )  [pure virtual]

Perform specific ray-tracing calculations instead of relying on the facets or patches. For example, a sphere can provide its intersection routine so the ray-tracing renders perfect spheres.

Parameters:
params The parameters (ray, hit ...)
Returns:
True if there is a valid intersection, false otherwise
