Ian Curtis	2c23268d88	Support microtexture relative scale. The exact scaling values are not known, but a 2x difference between each level seems highly likely. We know from visual inspection from scud that the first level is exactly 4. The SDK has a function that accepts a float input for scale and does this. lod = (1/scale) + 0.5. If lod>3 lod = 3. So this is our best guess.	2016-12-09 14:13:46 +00:00
Ian Curtis	483ba2f398	Fix the shading in scud. When lighting is disabled the fixed shading intensities appear to be offset values added to the colour value.	2016-11-11 17:50:27 +00:00
Ian Curtis	ef11990d19	Parse out scrollfog value used for blending over the 2d background.	2016-10-08 15:41:16 +00:00
Ian Curtis	c3581c9fe8	Support multiple microTextures, fixes crazy texturing in sega ski champ. I'm assuming microtextures are always located on the other memory bank to the base texture. This logic seems to work for all our games anyway.	2016-10-06 01:37:29 +00:00
Ian Curtis	c2b1db11f8	Cull geometry based on the culling distances in the nodes. Should give some sort of speedup on lower end pcs where the CPU is predominantly the bottle neck.	2016-06-16 20:05:29 +00:00

Ian Curtis	36074d9fd5	Y texture offsets are just 5 bits. Texture coordinate wrap around happens in the same texture sheet, not into the next one. Fixes various texturing bugs in sega rally.	2016-05-30 13:25:00 +00:00
Ian Curtis	2086b1c9af	Stencil layered polys, fixes shadow z fighting in some of the games. Other games maybe using stipple alpha (yuck), not sure yet.	2016-05-27 19:30:40 +00:00

Ian Curtis	f031e5d095	finish front/back face culling code based on matrix determinant. Optimised opengl to avoid redundant state changes.	2016-03-22 23:39:59 +00:00
Bart Trzynadlowski	34301e97e1	Adding new 3D engine by Ian Curtis. Old engine moved to Graphics/Legacy3D/.	2016-03-21 04:10:14 +00:00
