gameframe-virge

Everything GameFrame knows about the S3 ViRGE and its S3D Toolkit: texture and video formats with the texel layout each is, surface flags, rendering types, alpha modes, the S3DTK_STATEKEY names and the slots of S3DTK_FUNCTIONLIST. Texel decoding is gameframe-texel's.

Source: S3, S3D ToolKit SDK 2.6, S3DTK.H (published copy: https://github.com/kytulendu/S3DTK).

draw is the chip's drawing as the toolkit drives it: a State holding the S3DTK_SetState values, the 32-byte S3DTK_VERTEX_TEX record, and triangle_set drawing lists, strips and fans (Gouraud, with source-alpha blending) into an 8- or 15-bit surface through gameframe-raster. The wrappers/s3dtkw DLL and Un-POD's S3 renderer both draw with it.

Not here yet: texturing, fog and the Z buffer.
