Detailed Description

Resolves ray and box intersections for tools

This object can calculate intersections of basic primitives against the scene. This is intended for tools to perform interactive operations (like selecting objects in the scene). Note that much of the intersection math is performed on the GPU. This means that any intersection operation will probably involve a GPU synchronisation. This isn't intended to be used at runtime in a game, because it may cause frame-rate hitches. But for tools, it should not be an issue.

The documentation for this class was generated from the following files:

SceneEngine/IntersectionTest.h
SceneEngine/IntersectionTest.cpp
