Need new AABB vs. Ray algorithm #344

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Try doing ray vs BoundingBox collisions, when the ray is behind the box or 
the box has one very thin side.

What is the expected output? What do you see instead?
I expect all collisions to be reported as they occur, however sometimes the 
thin box won't register collisions, or the ray that is behind the box will 
return an incorrect result set.

An evaluation of the box vs. ray algorithm is required.
See this thread for test case:
