Python-Raytracer

A basic Ray Tracer that exploits numpy arrays and functions to work reasonably fast compared with a pure Python implementation.
The code is written keeping as much readability as possible.

• Refraction
• Thin film interference
• Textures
• Monte Carlo Ray Tracing with importance sampling
