LibTrace is a raytracing library that I (pauldoo) wrote in order to learn and understand how raytracers work. I was mostly interested in the maths/physics behind it so that's why it is only a library (ie, no frontend or fileparser).

By itself this raytracer can do nothing. You need to write a C++ program which will call the various functions provided.

Since then of course a few people have helped out to speed up and to implement new functions so it's not been all me.
