Ian Curtis bddc86aba9 The vertex shader is run before clipping is done. If fogging values are calculated and clamped in the vertex shader it can interpolate bad values, since the range has been truncated. This happens if the polys overlap the near plane. The solution to clamp the values in the fragment shader. This fixes a bunch of fogging errors I long thought were transparency related errors in the ocean hunter.		2017-11-20 22:21:15 +00:00

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	add missing header	2017-09-30 19:05:04 +00:00
New3D.cpp	Fixed shading also works with untextured polys. Fixes some shading issues in La machineguns. (Harry Tuttle)	2017-11-07 00:15:57 +00:00
New3D.h	Star wars is the only game to pass unsigned fixed shaded values (per vertex brightness) to the renderer. Originally we thought that the specular flag would turn on unsigned values since it's the only game to set specular with these polys, but this logic turned out to be incorrect. The JTAG interface seems to config the GPU to turn on this functionality. (Harry Tuttle)	2017-10-05 19:15:00 +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	Finish the hash function (Harry Tuttle)	2017-10-19 20:48:53 +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

R3DShader.h	Modern hardware does backface culling in window space by calculating the face normal for the polygon, then doing a dot product against the view vector. The real3d pro-1000 on the other hand passes a pre-calculated face normal for each polygon which is used for culling. We were using this face normal to rewind the polygons so that regular backface culling would work. This worked 99.9% of the time. However this was failing on some models in Virtua Striker. The reason was because the pre-calculated face normals being passed were actually completely different to the actual face normals for the poly (not just inverted like you would expect). This broke our code. The solution was to emulate face culling directly in the vertex shader using the pre-calculated face normals directly. Only minimally tested this but hopefully there are no obvious regressions.	2017-08-29 10:27:29 +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

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
