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/
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
- ...
