donut.c but in python!

• This project is inspired by the famous donut.c program and intends to produce similar, but different renders in python.
• Instead of rendering ASCII characters in terminal, it renders points in open-cv window which enables anyone to save the renders in the form of image/gif/video.
• You can simply reduce the theta_spacing and phi_spacing in donut.py to increase the number of points and thereby making the donut more "solid". I find the default render much more pleasing even though we can see through it sometimes 😅

Wait there's more!

• Along with rendering a simple donut, there is also a file to render 9x9 cube. Don't run cube_hollow_fast.py to render cube, it was a failed vectorized attempt to make the slow for-loop implementation fast. Instead, run cython_implementation/cube_hollow_fast_cython_run.py, which is cythonized code and runs 4-5 times faster than for-loop implementation.
• With the default arguments in cython_implementation/cube_hollow_fast_cython_run.py, the program renders just over a million points! you can tweek the arguments to make the render faster by rendering less points while maintaining close to a cube structure.
• python 3.10.11 is used in the project
