GPU 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.

Funny to see how it progresses:

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
• 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

Roadmap/todo

• undo/redo
• texture baking / batch baking
• more nodes: AO node, distance field,...
• multiple pass nodes
• misc parameters like baking directory,...
• compute node metadata by parsing GLSL shader code
• better parameter controls (sliders, color picker,..)
• node group/sub node: reuse a subnode in your new texture
• pin parameter controls and result from various nodes into one view
• Vulkan port
• Port to Linux (with SDL)
• ...
