PyTracer : Ray tracing with Python

PyTracer was a fun coding project I worked on back in 2017. The idea was inspired by MelRay which was a ray tracer written completely in Maya’s Mel language and done by my CG supervisor Clinton Downs at New Holland. 

Why not write a ray tracer in Python? That was the initial spark that triggered me to accept this challenge.

It took two months of my spare time. I had learned plenty of math and physics through the process. Camera, shadow ray, sampling, dof..... So many topics that I never thought about when I was using renderers in 3D programs. 

Of course the final product is not perfect, noisy, slow, can’t render anything but spheres and planes. And I still believe my hemisphere sampling is not correctly implemented. But I’m happy with the journey and the outcome is satisfying.

Again special thanks to Clinton for the resources and inspiration.
