A C++ implementation of the fast voxel traversal algorithm.

About

A prototype for the implementation of Amanatides & Woo's "A Fast Voxel Traversal Algorithm" in C++. Note, this has not been tested, and is not guaranteed to be bug-free. An overview of the algorithm can be found here.

Notes

• Instead of using double or float, I've decided to use value_type which can be set to a user-specified type in Vec3.h.
• An optional enhancement that can be done is calculating the ray's inverse direction upon construction of the ray. This will ensure inverse direction is calculated only once per ray.
