As a result of the rapid development spawned by @Mrneo240 's nuQuake, I've just tagged version 1.0 of GLdc, my Dreamcast OpenGL driver. Highlights: Partial, but wide-reaching GL 1 implementation Supports immediate mode and glVertexPointer et al. Dynamic memory allocation - doesn't allocate a bunch of memory upfront Mega fast near-Z clipping algorithm Supports VQ compressed formats as well as uncompressed Support for paletted textures via GL_paletted_texture and GL_shared_texture_palette extensions Leverages punch-thru polys to support GL_ALPHA_TEST, glAlphaFunc Lots more things! GLdc is part of the Simulant game engine project - feel free to contribute or join us on Discord!
Just coming in to say that I've been using GLdc for our upcoming game Reaperi Cycle and it's been working very well! And the recent developement is super welcome too!
