GPU Texture Generator

Imogen

GPU/CPU Texture Generator

WIP of a GPU Texture generator using dear imgui for UI. Not production ready and a bit messy but really fun to code. Basically, add GPU and CPU nodes in a graph to manipulate and generate images. Nodes are hardcoded now but a discovery system is planned. Currently nodes can be written in GLSL or C. Python is coming next.

Use CMake and VisualStudio to build it. Only Windows system supported for now.

Features:

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

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
• ...

Check the project page for roadmap.
