StapleButter f16d2aec61 calculate texture coordinates 2017-02-28 00:50:54 +01:00
StapleButter 8c2572e354 correct VRAM emulation.
there is room for optimizations esp. in the GPU drawing routines.

StapleButter dadf1eb5a5 fixes to 3D rendering. polygons are almost pixel-perfect. clipping still doesn't get colors quite right. 2017-02-20 18:46:44 +01:00
StapleButter abd2cb444b improve 3D renderer precision. not perfect, but not bad at all. 2017-02-17 04:07:00 +01:00

StapleButter 15c8d59e2b vertex colors, with Gouraud shading and all
has yet to be checked for whether it's accurate, optimized, etc...

StapleButter 050ba5dfbe some debuts of 3D drawing.
it can draw non-strip polygons, filled with a fixed color. oh and it doesn't work if they're facing back.
