fast3d — software RSP
A C++ interpreter that consumes the Gfx display list the game builds each
frame and emits OpenGL calls, replacing the Nintendo 64's Reality Signal
Processor and Reality Display Processor.
Origin and license
This code is adapted from the Perfect Dark PC
port (port/fast3d/), which in
turn is the Ship of Harkinian /
libultraship fast3d, itself descended from
sm64-port.
LICENSE.txt in this directory (MIT, © 2020 Emill, MaikelChan) covers that
lineage. glad/ is generated by glad

GoldenEye-specific work
The PD fast3d already handles G_TRI4 (GoldenEye uses it too). The GE additions
are the custom color-combiner / render modes and the handling of GE's GBI
extension commands. rsp/graphics/gmain.s (GE's real RSP microcode, in the
repo root) is the ground truth for the exact command encodings.
