PS3 OpenGraphics Toolkit - The Open Source Shader Compiler Replaces Cg-Toolkit

[Cruslan]

Greetings. I made a shader compiler for intended to use with PSL1GHT project, Replacing the only thing that remains closed sourced; NVIDIA Cg Toolkit. For now it has those features;

• A shader compiler --> Devired from Mesa's Nouveau drivers for knowledge. Its fully compatible with compile Shader Model 3.0(which RSX's GPU supports as feature-set).
• A shader deassembler --> Devired from RPCS3 RSX deassembler, slightly modified for working with CLI usage.
• A complete test suite, showing capabities of shader compiler in real hardware.

All parts of projects either gathered from open source knowledge or open source software. In future all the components of project will be compatible with PSL1GHT and its licensing model.

I believe RSX is hardest part of PS3 that work with, not because its hard but there aren't tools or documentation. With this toolkit i wanna improve PSL1GHT's capabilities in terms of graphics.

In future i wanna add those;

• A OpenGL wrapper, it can pull more developers on scene and make easier to develop complicated homebrew. I wanna integrate PS3GL project to toolkit and improve its feature set to OpenGL 2 level, which is capable with Shader Model 3.0.
• Code optimizations, in this state compiler creates bigger shaders than Cg Toolkit, some optimizations have to made.

For now project tested in those;

• https://github.com/Mayo1970/IoQuake3-PS3, works flawlessly with small code changes.
• https://github.com/Mayo1970/xash3d-fwgs, works flawlessly with small code changes.
• https://github.com/Cruslan/PS3-OpenGraphics-Toolkit/tree/main/testsuite, which tests all of shader features can compile.

I wanna talk about my project, are can we merge with PSL1GHT or at least improve the condition for future developers? I wanna hear your thoughs. My project is open sourcely available on GitHub, with all components can be compiled only with GCC. https://github.com/Cruslan/PS3-OpenGraphics-Toolkit/tree/main/testsuite
