Ray Tracing in One Weekend in C

This project is my implementation of the fantastic ray tracing project Ray Tracing on One Weekend by Peter Shirley. The original ray tracer (and it's extensions) are implemented in C++ but I wanted to write a ray tracer in plain C instead. Thus, all physics calculations implementations are very different since OOP and operator overloading are unavailable.
