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.

Controls

Key	Action
w	move forwards
s	move backwards
a	move left
d	move right
q	move up
e	move down
shift	move faster while held
escape	toggle mouse controls on/off
mouse	turn camera

Setup/Running

pip install -r requirements.txt
python3 main.py
