DRM/KMS fullscreen rendering without X or Wayland—rare for shader tooling.

Strengths

•Direct DRM/KMS rendering bypasses entire windowing system stack for embedded use.
•Shadertoy compatibility means existing shaders run without modification.
•PEP 723 inline dependencies enable single-file executable shader scripts.

Weaknesses

•Linux-only with DRM/KMS requirement limits audience significantly.
•No Windows or macOS support mentioned for cross-platform development.

Post Description

Shaderbang is a Python toolkit for OpenGL rendering using DRM/KMS on Linux. It renders fullscreen without requiring any windowing system, like X or Wayland, making it ideal for embedded systems and headless environments. It is compatible with shaders from Shadertoy, and can be used as a library to build interactive applications.

It supports hot-pluggable input devices — keyboard, mouse, touchscreen, and trackpad — via evdev for interactive rendering. Shader files can be made directly executable with shebangs, and Python scripts can embed their dependencies inline as single-file scripts using PEP 723.
