How I built a Ray Tracer in Pure Python
Arun Ravindran (~arocks) |
What started as a visually appealing Python project for teaching intermediate Python Programmers, building a ray tracer was an enormous learning experience for the author as well. It began with deciphering the intricate mathematics and physics behind image rendering. Translating them into idiomatic Python took several iterations until the code looked beautiful. Eventually the process of making entertaining video proved to be the most challenging of all.
In this talk, I want to cover my experience of exploring the world of Image Processing armed with nothing other than the Python standard library. I hope to help others who are interested in this domain and change perceptions about Python performance in general. This might also be of interest to content creators who would like to make videos about Python.

Basic knowledge of Python. Basic knowledge of Optics and Linear Algebra would help.
