F3DEX3 Support? about libdragon HOT 2 CLOSED

Thanks for reaching us.

libdragon is using a novel architecture for RSP programming which has nothing to do with commercial microcodes. We have a RSP framework called rspq, upon which our ucodes are written, which allows for lockless scheduling of single commands, continuous non-batched parallel execution, and transparent RSP overlay management.

For 3D graphics, we have a full OpenGL 1.1/1.2 implementation in the unstable branch, with a totally "from scratch" ucode. More information can be found here:
https://github.com/DragonMinded/libdragon/wiki/OpenGL-on-N64

The RSP code powering the OpenGL implementation can be read here:
https://github.com/DragonMinded/libdragon/tree/unstable/src/GL
(see the various files starting with rsp_).

Our microcode is already more advanced than F3DEX2 in some regards (eg: lighting on vertex colors), though in general it is not quite as optimized yet. We also develop iteratively on it, we don't have the issue of "fixing a release", because the ucode API is not part of the public API surface.

In addition to all of the above, the goal of libdragon is to provide a 100% open source and legal framework to develop on Nintendo 64. To the best of my understanding, F3DEX3 is derived from Nintendo proprietary code, it is thus unlicensed and unlicensable, and as such it cannot be legally used. This alone sets it outside of the scope of libdragon.

Ah, that makes sense. Thank you for the detailed explanation, rspq sounds like an fascinating approach!

Best of luck with this project, excited to see how this progresses in the future!
