be84bc9934 softgpu: Detect binner alloc fail and bail. 2023-01-01 06:59:14 -08:00
Unknown W. Brackets
a7b7bf7826 Global: Set many read-only params as const. 
This makes what they do and which args to use clearer, if nothing else.

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.

7880eb15c1 softgpu: Always use software skinning. 
There's only software skinning, after all.

80cccd7abb Build: Fix debug build on Windows 32-bit. 2022-10-01 17:07:27 -07:00
Unknown W. Brackets
6282f8b05f softgpu: Expand texture coords to include q. 
We'll need this to correctly project.

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.

Unknown W. Brackets
88b3b26ed3 softgpu: Cache reused indexed verts. 
This happens a lot for spline/bezier, so can significantly speed up curve
heavy scenes.  Isn't necessarily that common otherwise, though.

6877ff1af2 softgpu: Fix state/continuation for imm prims. 2022-09-18 06:16:26 -07:00

596b07bd2e softgpu: Support fog and color1 on imm verts. 2022-09-18 06:16:26 -07:00

35ba01e01f softgpu: Refactor imm draws to bypass vert read. 2022-09-18 06:16:25 -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.

Unknown W. Brackets
028a341cc8 softgpu: Explicitly flush on sync and output. 
We could in theory skip flush on FinishDeferred, and allow some CPU/GPU
overlap.  If we did, we'd still want to flush at these times.

ce4fee7373 softgpu: Refactor triangle cull processing. 2022-09-11 22:39:32 -07:00
Unknown W. Brackets
8a6e8066bf softgpu: Store vertex colors as packed RGBA8. 
No need to keep it expanded at 4x the space for both colors.

8c55e18ea8 softgpu: Switch vert continue buffer to members. 
Better this than static.  May be easier to handle imm prims correctly.
 2022-09-11 08:54:34 -07:00
Unknown W. Brackets
88e8f95293 softgpu: Flush on transfer to pending tex read. 
Potentially could use these for self-render, but so far we should be
detecting that so leaving it alone.

1bc3acf2ed softgpu: Use a const for subpixel screenpos factor. 2022-02-19 21:03:49 -08:00
Unknown W. Brackets
a66377fdf1 softgpu: Remove offset from screenpos. 
This simplifies tighter calculations, and reduces the common magnitudes
we'll be dealing with.
 2022-02-19 20:38:44 -08:00
Unknown W. Brackets
61e30e8f8b softgpu: Fix cull in throughmode. 
Was only an issue for triangles used to draw rectangles, but caused our
test to fail.

Also move a test that was failing due to an outdated prx to passing.

Unknown W. Brackets
76f9103e97 softgpu: Add a table and initial dirty flags. 
Not actually using the dirty flags to skip state, but have moved to
Execute_* functions and everything else like other graphics backends.

Unknown W. Brackets
c0c3f7284a softgpu: Avoid flush texturing from stride. 
This generally detects overlap more accurately using a dirty rectangles
approach.  Also detects render to self much more accurately, including
with depth.

3e4d768e7a softgpu: Pack vertexdata a bit better. 
This reduces the BinItem size by 15%.

12a4c63fc7 softgpu: Precompute state for vertex transform. 
Doesn't help a ton, but with lots of verts can improve a percent or two.

2797e035df softgpu: Precompute lighting parameters. 
In many cases, games use lighting just for diffuse or something, this
helps skip what's not needed too.  Good improvement in a scene from a
Naruto game.

d95475e021 softgpu: Expose flush reasons/times in debug stats. 2022-01-16 11:27:42 -08:00

cc155ec460 softgpu: Avoid texture/CLUT flush unless overlap. 
Only need to flush here if there's some overlap in the target.

d6fa301ab1 softgpu: Track CLUTs as states for binning. 
This way we can have multiple CLUTs in process at once, which helps.

18f2a45a6a softgpu: Allow binning across prim calls. 2022-01-16 00:49:49 -08:00

6896a7a64e softgpu: Use cached state for screen offset. 2022-01-15 18:20:25 -08:00
Unknown W. Brackets
02c5559393 softgpu: Remove z from DrawingCoords. 
It's not really used much of anywhere, anyway.

f091225572 softgpu: Stop storing model pos. 
We don't even use this anywhere else.  Also skip needless Lerp on clip.
 2022-01-14 20:36:09 -08:00
Unknown W. Brackets
d6a8cb2a0e softgpu: Stop storing normal/worldnormal/worldpos. 
This is only needed for lighting, which is applied right away.

This improves perf just simply from less data being copied.

5bb6245b1f softgpu: Fix leaked range flag on cull. 
Fixes some backgrounds in Final Fantasy 4, probably others.
 2021-11-14 08:43:52 -08:00
Unknown W. Brackets
ac60e2ecd4 GPU: Track HW tess at start of frame too. 
This also makes it so we don't force the setting off when you change
backends, and just ignore it if unsupported.

8a7ec4fc19 GPU: Fix curve breakage due to cull flipping. 2018-12-16 13:00:36 -08:00

Unknown W. Brackets
8187927b9d SoftGPU: Use vertexjit for submitted primitives. 
This uses the standard cache other rendering uses.

In Legend of Heroes 3, for example, this provides a 10% speed improvement.

01076dd959 SoftGPU: Don't wrap negative positions. 
Haven't fully verified this, but without this, Gods Eater Burst's bloom
doesn't work, since -1,-1 maps to 1023,1023 so everything is clipped.
 2017-05-13 17:28:38 -07:00
Unknown W. Brackets
1666586869 SoftGPU: Implement CONTINUE prim type. 
Matches tests (except 3D lines, which aren't implemented yet.)

dfed20701a SoftGPU: Correct negative coord handling. 
Fixes  - we need this signed to handle negative values properly.
