Public Attributes
real	tmin
	start parameter of the ray.
real	tmax
	end parameter of the ray.
Ray3D *	ray
	a pointer to the ray.
RayHit3D *	hit
	a pointer to the result of the intersection.
int32	originInstanceIndex
	index used in the instance grid to identify each instance
int32	originSubIndexIndex
	index used in the by some some raytracable primitive to identify a sub instance (example: a leaf in a tree)
int32	originFacetIndex
	index of the facet of the instance that should excluded
void *	additionalInfos
	used in TGrid to do something else than just finding the first rayhit. For example storing all the instances intersected by the ray.

Detailed Description

Structure used when searching for the intersection of a ray and an object

The fields originInstanceIndex,originSubIndexIndex and originFacetIndex are used to identify a particular triangle that is excluded from intersection calculation (usually the origin of the ray for a reflected ray). If you do not want to provide such a triangle, just use -1 in all those fields.
