A simple implementation of a visual shader graph tool. Shady:
- Allows visual editing of shader graphs
- Allows interactive experimentation with shader settings in real time.
- Is extensible, adding new shaders/effects will be straight forward.
- Allows save and load of shader graphs.
Not because the world needs one so much as that I need to build one. It's a playground for testing shader ideas, experimenting and learning.
Shady! is very much a work in progress. Right now it has a minimal set of transforms, basically beyond save and load it suports only Brightness and RGBA channel splitting.
The focus at the moment is to get the core capabiities of load/edit/save working correctly before expanding the number and types of supported transforms.
The current TODO list is really just implementing core editing functionality:
- Implement the Save menu
- Allow editing of Config in nodes
- Allow editing names
- Enable force re-evaluation of graph/nodes
After that there will be more xforms
- Contrast/Blur/Sharpen/Curves, LUTs
- Custom shaders (BYO GLSL)
Currently Shdy! is supported on my M1 MacBook Pro :)
The libraries I'm using are more or less platfrom independent and so cross-platfrom support should be straightforward but it's not my primary focus right now. A sufficiently motivated engineer should be able to port it to Linux or Windows flavours.
* OpenGL 4.1 : Because.
* GLFW : To handle windowing and context
* ImGui : For UX widgets.
* STB : Single file for load and save of images
* NlohmanJson : `JSON` parsing for loading saved graphs.
