示例1: Find_Intersection
bool Find_Intersection(Intersection *isect, ObjectPtr object, const Ray& ray, BBoxDirection variant, const BBoxVector3d& origin, const BBoxVector3d& invdir, const RayObjectCondition& postcondition, TraceThreadData *threadData)
{
if(object != NULL)
{
DBL closest = HUGE_VAL;
if(object->Intersect_BBox(variant, origin, invdir, closest) == false)
return false;
if(object->Bound.empty() == false)
{
if(Ray_In_Bound(ray, object->Bound, threadData) == false)
return false;
}
IStack depthstack(threadData->stackPool);
POV_REFPOOL_ASSERT(depthstack->empty()); // verify that the IStack pulled from the pool is in a cleaned-up condition
if(object->All_Intersections(ray, depthstack, threadData))
{
bool found = false;
double tmpDepth = 0;
while(depthstack->size() > 0)
{

// TODO FIXME - This was SMALL_TOLERANCE, but that's too rough for some scenes [cjc] need to check what it was in the old code [trf]

}
