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 : http://skaven.fr/imogen/ 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

Features:

• 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
• ...
