[Patch] Reduce runtime memory allocations in Dbvt #574

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
This is second patch in addition to #573. 
Combined together they give me zero runtime allocations, at least in 
environment where objects don't move. 

I found that in comments for rayTestInternal() it states that function uses 
persistent stack but actually it's local. So I changed it to persistent. I hope 
this doesn't introduces some bugs with parallel configurations (they should 
uses static rayTest with local stack, right?).
