GPU/CPU Texture Generator

GPU Texture generator using dear imgui for UI. Not production ready and a bit messy but really fun to code. This is an hybrid project that can run natively or on the web (thanks to emscripten). Basically, add GPU and CPU nodes in a graph to manipulate and generate images. A web build is available here : Image of Imogen 0.13 Web Edition Currently nodes can be written in GLSL or C or Python.

Use CMake and VisualStudio to build it. Windows and web builds are available.

Web Edition limitations:

  • no threaded jobs
  • no C/Python nodes
  • no Python plugins
  • no file load/save


  • Node based texture editing
  • material library browser
  • edit/change node shaders inside the app
  • bake textures to .png, .jpg, .tga, .bmp, .hdr, mp4
  • PBR preview
  • timeline for parameters animation

Currently implemented nodes

  • circle and square generator
  • sine generator
  • checker transform
  • transform
  • Mul/Add
  • smoothstep
  • pixelize
  • blur
  • normal map from height map
  • sphere/plan previewer
  • Hexagon
  • Mul-Add colors
  • Blend (add, mul, min, max)
  • Invert color
  • Circle Splatter
  • Ramp
  • Tile
  • Polar coordinates
  • ...
