Detailed Description

An axis-aligned bounding box.

The rayIntersect and rayIntersectT functions are implemented using a modified version of the Williams BBox test. Currently the preprocessor define ORIGINAL_WILLIAMS (in math/Ray.h) will cause the code to use the original Williams BBox test instead of the modified version.
