DoRayMe

A Quick and dirty raytracer.

This raytracer is made following the book «The Ray Tracer Challenge» by Jamis Buck.

It is writen in C++ with no STL and use LodePNG to output PNG file and use them as texture, also use NanoJPEG to use jpeg file as texture, and can use use Lua 5.3 for 3D pattern definition and more to come on the Lua side later..
