About
This is a simple raymarching/sphere tracing renderer I wrote over the course of about a week in early 2020. The rendering is all done in a GLSL shader, the window/input stuff is managed with python.
Code Overview
| file | description |
|---|---|
raymarch/shaders/shader_load_helper.py |
handles loading of shader files, including a (somewhat janky regex based) #include handler |
raymarch/shaders/fragment_shader.frag |
most of the rendering stuff is in here |
main.py |
manages window, keyboard/mouse input, etc. |
