Henrik RydgårdandClaude Opus 5.5 e03f6b80cd SoftGPU: Keep textured rectangles as triangles unless they'd match 
Each triangle of a quad has its own UV planes, which a sprite built from the
corners doesn't reproduce. Textured triangle rectangles now only become
sprites in through mode with nearest filtering. Gears of Destiny's text boxes
become bit exact against the PSP, and no dump compared gets worse.

Henrik RydgårdandClaude Opus 5.5 497f5628fd SoftGPU: Keep rectangles as triangles where sprite coverage differs 
Strips, fans and triangle pairs that form rectangles are drawn as sprites,
but a sprite's first column is (x + 6) >> 4 and a triangle's (x + 7) >> 4.
For a left edge 9/16 into a pixel, draw them as triangles (NBA 2K13's menu
boxes, now 99.99% exact against the PSP).

Unknown W. Brackets 1931fa2f5f softgpu: Make triangle fan rect detection generic. 2022-10-16 16:01:09 -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.

Unknown W. Brackets 288d18447d softgpu: Detect full triangles as rectangles. 
Seen in a dump from Infected, improves FPS ~25% there.

Unknown W. Brackets 3d4c1548b6 softgpu: Allow tri -> rect in transform. 2022-02-12 12:03:55 -08:00
Unknown W. Brackets 259b10d42a softgpu: Turn more tri strips into rects. 
This catches a common case in Valkyrie Profile.
Rotation is resolved by just always using tl/br.

Unknown W. Brackets 2381f355c2 softgpu: Combine tris to rects with ignored z too. 2022-02-12 11:33:36 -08:00
Unknown W. Brackets 48ef4a18b1 softgpu: Handle scissor/range in BinManager. 2022-01-13 19:07:41 -08:00
Unknown W. Brackets a0a9b1e89b softgpu: Add class to manage and enqueue for bins. 
For now, just forwarding.

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.

Unknown W. Brackets 2ab7499d8d softgpu: Combine sliced rectangles. 
This mostly affects clears, and reduces overhead.  Only about 2%
improvement, but it's a small change.
 2021-11-14 18:31:46 -08:00
Unknown W. Brackets fb6fadbbb7 softgpu: Fast path rectangles as fans. 
Some games, such as Legend of Heroes III, use fans instead of strips.

Henrik Rydgård 970adfbcc9 Isolate most of the softgpu specialization code to RasterizerRectangle. 
See comments.
