My hope is that people will use this to build cool ***or improve on some of the existing cool addons out there.
Static 3D meshes, some basic shapes, images, textures, and animated textures are supported.
This supports both Lua addons and plugins but it's designed to be easy for Lua addon devs to drop in the library and start using it.
Everything is rendered respecting the games actual depth buffer as you can see in this sample demo gif with my dog Rikku in FFXI.
I have rendered millions of triangles on screen with no impact to performance in testing.

3D Animations were excluded because it's more work and I'm not sure anyone would use it.
In the future I would like to add support for attaching to character bones and nameplates.
More details in the readme. If anything is vague/unclear, if you find bugs, or if there's a feature you think would be useful here, I'd appreciate the feedback.
I have included some precompiled libraries so you can drop them in and go but the source code is all there if you want to build it yourself.
This is absolutely AI assisted but hopefully not slop!
