Traycer is a little Ray-Tracer written in C++. Ray tracing is a rendering technique for generating an image by tracing the path of light as pixels in an image plane and simulating the effects of its encounters with virtual objects.

Project inspired by a little ray tracing project I made in C as part of my third year at Paul Sabatier University.
