Detailed Description

Describes all the information used to raytrace an instance. See I3DShGroup::GetRaytracedInstances(). The raytraced instances are different from I3DShInstance ! The reason for that is Master Groups. If an instance is placed in a Master Group and the Master Group is instanced twice, there is still only once I3DShInstance however there will be two RaytracedInstance with a different global transform (the transform of I3DShInstance is local to the Master Group that contains it) The index (fIndex) defines a unique identifier over all the raytraced instances.
