A simple Python and JavaScript (WebGL) framework for running GLSL demos and Monte Carlo image generation, e.g., raytracers. Similar to Shadertoy in basic functionality but runs locally.

Usage

python glsl_bench.py examples/basic/conf.json

or

python3 -m http.server 8000 --bind 127.0.0.1
# open: http://localhost:8000/?shader=examples/black-hole/black-hole.json

Features

• Binding variables such as mouse, time and previous_frame to GLSL uniforms using a JSON configuration file.
• Specifying textures in configuration files
• Image output in raw float (.npy) and PNG formats

Python dependencies: Install as pip install -r requirements.txt
