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.
