ShaderChain is an open source GLSL fragment shader composition engine for realtime and offline rendering.

This is beta software. Please don't expect everything to be working perfectly. I'm happy to support by email or Discord. Video input doesn't work perfect with offline rendering.

FEATURES

  • Build a shader stack with each rendered texture input to the next pass
  • Define uniforms with JSON which map to UI and MIDI
  • Serialize shader chains and uniforms to presets
  • Create texture uniforms with video, webcam, microphone, sound files, framebuffer swaps, or other passes
  • Render to PNGs, encode mp4s and gifs (ffmpeg required - install here)
  • Gif encoding supports setting number of colors and scaled resolution
  • Mp4 encoding supports looping video
  • Use precise duration and framerate for slick looping gifs 馃ぉ
  • Build a midi map with the UI
  • Livecode by going full screen and hiding the UI (bring your own editor)
  • Frame averaging for motion blur
  • Wasd+mouse camera control uniform
  • Audio accumulator uniform (by Eris Fairbanks)
