Mat4.cpp	Adding new 3D engine by Ian Curtis. Old engine moved to Graphics/Legacy3D/.	2016-03-21 04:10:14 +00:00

Model.cpp	We were force normalising the result of matrix * normal, which looked correct in most cases. But this didn't preserve the scaling of the matrix, or the scaling of the model normals which resulted in many over bright areas. On it's own this generally worked, but games like Star Wars looked quite broken. Harry correctly figured out if you scale these normals by the scaling value that is sometimes present in the culling nodes the lighting looks correct. Still more work to do to correctly figure out the model3's lighting model.	2017-07-29 16:30:30 +00:00
Model.h	Harry made some important discoveries with regards to fixed shading on the model 3 (per vertex poly brightness values). Firstly values are allowed to be negative, and they are used as a drop in replacement in the standard lighting equation for the normal dot light vector. This quite radically changes the brightness in LA Machine guns, but now correctly matches the arcade.	2017-08-19 20:06:31 +00:00
New3D.cpp	cosmetic	2017-08-21 23:00:29 +00:00
New3D.h	Finish fixed shading for 2.0 hardware. I'm pretty sure it actually works identically to step 1.5 hardware. The oddball is LA machine guns where the viewport ambient doesn't seem to effect the brightness. But the ambient works differently in this game because it uses the unclamped light model. Still need to investigate if the diffuse factor effects fixed shading.	2017-08-15 23:21:57 +00:00
Plane.h	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
PolyHeader.cpp	Fixed shading (per vertex poly colours) on step 1.5 hardware have the viewport ambient value added to them. This fixes various shading on scud. To do this had to switch the maths to the vertex shader.	2017-08-14 09:14:06 +00:00
PolyHeader.h	There are 2 bits in the polyheader labelled discard. When both are set ie in sega rally, the polygons are totally discarded. Scud seems to set bit 1 which seems halve the opacity.	2017-04-15 19:00:46 +00:00
R3DData.h	add LOD table data. Maybe we can get clipping planes out of these	2016-03-28 20:11:46 +00:00
R3DFloat.cpp	refactor	2016-06-19 21:43:09 +00:00
R3DFloat.h	Virtua fighter has a few massive polys that shouldn't be visible. It looks like these polys have a bad matrix, but the node distances are all zero. This means the bounding box that encapsulates them is of size zero. Skipping over these entirely seems to fix the issue.	2017-04-12 15:47:57 +00:00
R3DScrollFog.cpp	Fix attribute locations. glBindAttribLocation must be called linking	2017-08-11 11:59:41 +00:00

Texture.cpp	remove debug code	2017-06-20 19:46:06 +00:00
Texture.h	Originally to do mipmapping, I just used the base texture and then let the h/w automatically generate the mipmap chain. I wasn't sure the real3d api even exposed to the programmer the ability to directly set the mipmap data. Anyway, as pointed out by HarryTuttle scud actually uses darker mipmaps for an effect on the water. This patch uses the uses the actual mipmap data from the real3d memory. Only tested scud, so hopefully I didn't cause any cataclysmic errors :)	2017-03-24 13:38:20 +00:00
TextureSheet.cpp	Just use 1 hash map for the textures, instead of 1 for each format. Should greatly speed up texture invalidation. TODO invalidate texture mipmaps .. the h/w actually seems to stream the mipmap data separate from the base textures in some cases.	2017-03-24 20:54:12 +00:00

VBO.h	WIP	2016-03-24 13:17:17 +00:00
Vec.cpp	Fixes for non-Windows builds: Makefile updated and fixed header files in Vec.cpp	2016-04-05 04:30:52 +00:00
Vec.h	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
