Ian Curtis	5b9741bd5d	Support high priority polygons. They are treated as a separate overlay plane by the h/w. Fixes some missing fx in harley.	2017-02-20 17:22:32 +00:00
Ian Curtis	24cbeed526	Dynamically calculate near/far frustum planes for each viewport priority layer by clipping the overlapping meshes with the 4 frustum planes. A bit brute forcy, but the results are great.	2017-02-07 14:05:03 +00:00
Ian Curtis	c82dc55485	cosmetics	2016-12-22 22:11:19 +00:00
Ian Curtis	72dd0dbf98	only need to cull against 4 clipping planes	2016-12-22 22:09:13 +00:00
Ian Curtis	da8b63b44b	The model3 shares vertices between polygons. But it also seems to do this for polygons with different textures. This means the texture coordinate for potentially different sizes textures is shared. Currently this was broken leading to some corrupted looking textures. The fix is to simply cache the old texture coordinates, and recalculate the normalised coordinates in the new texture coordinate space.	2016-12-06 14:39:46 +00:00
Ian Curtis	10a5d2c0e1	refactor	2016-12-06 12:25:34 +00:00
Ian Curtis	fe60d115d2	Revert changes .. if we clip against the real3d clipping planes, our wide screen hack won't work anymore.	2016-11-26 01:19:51 +00:00
Ian Curtis	665fa90425	Get clipping planes directly from the viewport data. Also no need to clip against a far plane	2016-11-26 01:12:08 +00:00
Ian Curtis	f0a15febd1	implement scroll fog, fixes a tonne of missing fx	2016-10-09 16:34:12 +00:00
Ian Curtis	85c4d85562	refactor	2016-06-19 21:43:09 +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	5081ee99dc	Add code to convert the 16bit float format used by the hardware back into float 754 format. 16bit floats are used for the culling radiuses in the nodes.	2016-06-03 00:01:34 +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	ff8d311dcc	support colour table pointer	2016-05-18 23:06:41 +00:00
Ian Curtis	43add90d2f	Fix bad texture seems	2016-05-09 16:26:34 +00:00
Ian Curtis	ded3168060	Split face colour from per vertex poly colour. Fixes colour bleeding between connected polys in harley.	2016-05-07 15:28:04 +00:00
Ian Curtis	58d187e59a	parse viewports in normal order	2016-04-19 22:05:12 +00:00
Ian Curtis	057ee94210	simplify	2016-04-18 14:06:10 +00:00
Ian Curtis	aee89390ba	add LOD table data. Maybe we can get clipping planes out of these	2016-03-28 20:11:46 +00:00
Ian Curtis	4992e59673	Cache rom models, for better performance.	2016-03-26 22:44:26 +00:00
Ian Curtis	0327db246f	WIP	2016-03-24 13:17:17 +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
Ian Curtis	e7eb912eaa	add maths functions	2016-03-22 13:47:28 +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
