Henrik RydgårdandClaude Opus 5.5 f48251c90a SoftGPU: Cull primitives by z like the GE 
The GE counts a vertex as outside when |z| > w, comparing the float24 clip
coordinates without dividing, and culls a primitive only when all its vertices
are outside, with depth clamp on or off. Points were never culled, and lines,
triangles and rectangles were culled on a single outside vertex with clamp off.
Measured with gpu/probe for every primitive type, both clamp modes and a
range of w.

Henrik Rydgård 3e198c53b2 More include cleanup 2024-12-18 13:57:26 +01:00
Unknown W. Brackets 8f404a1961 softgpu: Fix minor typo. 2023-07-25 19:42:36 -07:00
Unknown W. Brackets dc962094f8 softgpu: Correctly fix inversions, matching tests. 
Inversions are allowed just fine, but if clipping results in coordinates
outside range, the triangle should be culled.  Fixes more wanted
inversions.
 2022-11-30 23:20:39 -08:00
Unknown W. Brackets 909f3feaea softgpu: Allow inversions when w >= -1.0. 
This seems to match desired cases well, see #16131.  Likely still
inaccurate to what hardware actually does.
 2022-11-26 12:11:56 -08:00
Unknown W. Brackets 71b4407889 softgpu: Throw away all inverted polygons. 
This is actually incorrect in some cases, but there are a number of games
affected by inversions, and they're practically always undesired.
 2022-11-19 20:30:49 -08:00
Unknown W. Brackets a66056217f softgpu: Avoid splitting rectangles for fog. 
If the fog factor would result in the same amount of fog, we're just
adding more work for no reason.
 2022-11-13 09:23:06 -08:00
Unknown W. Brackets 21064edfca softgpu: Correct tex on fogged rectangles. 2022-11-13 09:17:29 -08:00
Unknown W. Brackets d33986a5ad softgpu: Cull a triangle with all negative w. 
Per tests, this seems to happen but only when all points are below zero.
 2022-10-15 11:49:28 -07:00
Unknown W. Brackets 23af9be9f4 softgpu: Handle rectangle texture projection. 2022-09-26 18:44:39 -07:00
Unknown W. Brackets 8376176b2f softgpu: Split clippos out of rasterization vert. 
We don't use it, except w, at all in rasterization, so no need to keep it
in the bin queue.
 2022-09-26 16:50:40 -07:00
Unknown W. Brackets de080e2594 softgpu: Simplify vertex range culling. 
The previous logic was harder to understand and easier to get wrong.
Just drop them when clipping the primitive.
 2022-09-18 06:16:25 -07:00
Unknown W. Brackets 7a83f8bab5 softgpu: Use vertType prim override for flags. 
These parameters are a real shame, was so clean before...
 2022-09-06 22:20:45 -07:00
Unknown W. Brackets cc6491342e softgpu: Prepare dedicated rectangle path. 
We're still sometimes using the slow rect-as-triangles path, let's do
something faster.  As a first step, just handle binning.
 2022-02-20 09:38:51 -08:00
Unknown W. Brackets 8e7bc80e4b softgpu: Avoid modifying source vertex data. 
This was dangerous for strips and fans, which reuse the verts for
subsequent primitives.

Henrik Rydgård eba93f2ee0 Merge pull request #15340 from unknownbrackets/softgpu-textures 
Correct UV rotation and through mipmaps, optimize texenv blend a bit
 2022-01-24 08:19:34 +01:00
Unknown W. Brackets 818d17183b softgpu: Correct clear mode dither. 
It does apply, but have to be careful about alpha.
 2022-01-23 12:39:50 -08:00
Unknown W. Brackets 648b71616e softgpu: Correct UV rotation for transformed rects. 2022-01-23 08:15:15 -08:00
Unknown W. Brackets abef17caca softgpu: Simplify mask check. 
This performs a bit better.
 2022-01-16 23:40:57 -08:00
Unknown W. Brackets 89bc87a388 softgpu: Reduce copying during clipping. 
Common case is nothing needs to be clipped.
 2022-01-16 23:33:46 -08:00
Unknown W. Brackets cf3384c993 softgpu: Avoid double calculating screenpos. 2022-01-15 11:22:36 -08:00
Unknown W. Brackets a0a9b1e89b softgpu: Add class to manage and enqueue for bins. 
For now, just forwarding.
 2022-01-13 09:26:59 -08:00
Unknown W. Brackets d5c5e9478e softgpu: Prepare more state per prim call. 2022-01-10 22:12:35 -08:00
Unknown W. Brackets d7a82ab7b8 softgpu: Compute func IDs once per batch of verts. 
This saves a decent chunk of time, especially when many verts are being
drawn.
 2022-01-10 22:12:35 -08:00
Unknown W. Brackets 6367d5dc8f softgpu: Draw top left of rectangles first. 
This helps when things do self-rendering, since this way we won't read
from things we've just written to when scaling down.  See #11623.
 2022-01-08 20:53:01 -08:00
Unknown W. Brackets 8db2d37e64 softgpu: Fix depth cull in softgpu. 
Was improperly skipping cull for positive Z.
 2021-11-05 21:38:13 -07:00
Unknown W. Brackets 121c56e6db softgpu: Clip only on -Z, cull if entirely outside. 
This is important for several issues, like #12058 or #12060, where
something is drawn entirely outside valid Z, and should be culled.
 2021-09-09 20:13:42 -07:00
Unknown W. Brackets f32f89dd90 Global: Remove some unused variables. 2021-02-15 11:59:45 -08:00

Henrik Rydgård 2e06386cf6 Software renderer clipper: Don't clip on the sides. Fixes #4845 and should fix #7124 for the SW renderer. 2020-08-16 21:38:07 +02:00
Henrik Rydgård 970adfbcc9 Isolate most of the softgpu specialization code to RasterizerRectangle. 
See comments.
 2019-10-28 09:33:30 +01:00
Henrik Rydgård 86c781e434 Hack around most of the problems with the save/load dialog. Software stretch gets enabled in non-wide mode, so wallpapers work at a cost of speed. 2019-10-27 20:55:32 +01:00
Henrik Rydgård 290e9971a7 More specialization work. 2019-10-27 20:54:36 +01:00
Henrik Rydgård 9099441973 Darkstalkers: Gross hack to avoid the game's own stretch, and present the raw buffer instead for a sharper image. 2019-10-27 20:54:36 +01:00
Henrik Rydgård 2dd7a9aa12 More darkstalkers work 2019-10-27 20:54:36 +01:00
Henrik Rydgård c7f6724f7e Detect sprite drawing (1:1 texture mapping), run a simpler function without the triangle state tracking. 
This will allow further simplification and specialization.

Unknown W. Brackets 11a8857a7e SoftGPU: Correct clipping for flat shading. 
It needs to use the provoking color, regardless of culling or clipping.

Fixes Blade Dancer lighting (see #4140.)
 2018-11-22 17:48:55 -08:00
Unknown W. Brackets 817b5d7c1c SoftGPU: Support fog on 3D rectangles. 2018-09-09 23:59:48 -07:00
Unknown W. Brackets e22cc7ef6d SoftGPU: Always clip, without special neg z case. 
Depth clamping doesn't change whether it clips.  Also, avoid culling when
a vertex is behind the near plane.
 2018-08-05 17:47:05 -07:00
Unknown W. Brackets 77f0499f7f GPU: Rename clipping flag to depth clamp. 
It seems to just to depth clamp.  When depth clamp happens, it affects
clipping a little, but only for vertices that needed clamping.
 2018-08-05 17:11:51 -07:00
Unknown W. Brackets b94ca6e75e Vulkan: Use depth clamping, where available. 
This fixes, for example, Shadow of Destiny, even without the hack.
 2017-12-26 16:54:39 -08:00
Unknown W. Brackets ed34cf06b8 SoftGPU: Add a clear mode fast path. 
This skips a lot of extra work for clears, which are pretty common.
 2017-11-11 21:04:32 -08:00
Unknown W. Brackets 9d64597fb3 SoftGPU: Clip lines entirely outside early. 
Some were getting through, which may mean the line clipping isn't working
so well...
 2017-05-14 18:28:47 -07:00
Unknown W. Brackets e4f2ff1464 SoftGPU: Implement lines in transform mode. 2017-05-14 16:10:59 -07:00
Unknown W. Brackets b2d3058386 SoftGPU: Correct fog for rectangles. 
Gods Eater Burst uses fog in its bloom, with rectangles.
 2017-05-13 17:27:34 -07:00
Unknown W. Brackets dfed20701a SoftGPU: Correct negative coord handling. 
Fixes #5159 - we need this signed to handle negative values properly.
