A (nearly) pure Ray Tracing Project for Python

This work is based off the books Ray Tracing in One Weekend but ported to python

dependencies include:

1. pypy3 (note all other dependencies must be installed within pypy3)
2. numpy
3. matplotlib
4. tqdm
5. noise

1. Install Anaconda
2. conda env create -f environment.yaml
3. conda activate PyTrace_env
4. pypy3 -m ensurepip
5. if on mac you may need to fake a linked library described here
6. pypy3 -m pip install -r requirements.txt
7. pypy3 main.py

Technically, you can run w/o pypy3 installed but it is very slow w/o the JIT compilation, as seen below
