Henrik RydgårdandClaude Opus 5.5 0f2b5613fb SoftGPU: Interpolate Gouraud color and perspective UVs like the GE 
Both use the GE's fixed point depth plane. Color is screen-linear, also in
transform mode, with 8-bit channels as the plane values (gpu/probe exp54). For
perspective UVs, s = u * R(w), t and q = R(w) become 15-bit integers at the
triangle's largest exponent, go through the plane, and u = s * R(q) per pixel
(exp55-56, bit exact at 1/16 texel).

Henrik RydgårdandClaude Opus 5.5 524fac1c32 SoftGPU: Clip at the near plane like the GE 
Measured with gpu/probe exp43-47, bit exact:
- New vertices are interpolated from the inside vertex, t = d_in / (d_in -
  d_out) with d = z + w through the GE adder, using the GE's reciprocal;
  out - in is truncated to float24 before the multiply by t, and t and each
  coordinate use float24 products and adds.
- With one vertex outside, the quad is split from the vertex before it in the
  GE's order: (p, a, b) and (p, b, n). The GE takes odd strip triangles in
  reverse and fan triangles in order, so SendTriangle now says when the
  vertices it gets are reversed from that.

Henrik RydgårdandClaude Opus 5.5 93f57a4f38 GPU: Delete copy operations on classes that own resources 
These own GPU objects, memory or refcounts in their destructors (or assert
there that they were torn down), so a copy would double-free. Nothing copies
them today; this keeps it that way. The manager base classes cover every
backend's subclass.

Henrik Rydgård 623545bd24 Delete the "Hardware tessellation" feature. 
Very hard to maintain and debug, not worth it.

Henrik Rydgård bb573e6e0c Well, it builds, but doesn't work yet. 2026-06-02 12:33:53 +02:00
Henrik Rydgård a317890c08 Remove the GPUDebugInterface class 
Just a pointless extra layer in the class hiearchy, making it
unnecessarily hard to modify the interface.

Might as well hit GPUCommon directly.

Unknown W. Brackets 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.
 2022-12-10 21:13:36 -08:00
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 7880eb15c1 softgpu: Always use software skinning. 
There's only software skinning, after all.
 2022-11-06 08:44:22 -08:00
Unknown W. Brackets 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.
 2022-09-26 17:13:14 -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 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.
 2022-09-22 18:27:59 -07:00
Unknown W. Brackets 6877ff1af2 softgpu: Fix state/continuation for imm prims. 2022-09-18 06:16:26 -07:00
Unknown W. Brackets 596b07bd2e softgpu: Support fog and color1 on imm verts. 2022-09-18 06:16:26 -07:00
Unknown W. Brackets 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.
 2022-09-18 06:16:25 -07:00
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.

Unknown W. Brackets 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.
 2022-09-11 18:41:06 -07:00
Unknown W. Brackets 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.

Henrik Rydgård e6403d7157 Split GetPointer into two versions, to help with const correctness 2022-07-24 13:26:19 +02:00
Unknown W. Brackets 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.
 2022-01-25 19:07:33 -08:00
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.
 2022-01-23 08:08:40 -08:00
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.
 2022-01-20 18:39:01 -08:00
Unknown W. Brackets 3e4d768e7a softgpu: Pack vertexdata a bit better. 
This reduces the BinItem size by 15%.
 2022-01-19 23:17:09 -08:00
Unknown W. Brackets 12a4c63fc7 softgpu: Precompute state for vertex transform. 
Doesn't help a ton, but with lots of verts can improve a percent or two.
 2022-01-16 21:31:52 -08:00
Henrik Rydgård bdc69f5171 Merge pull request #15317 from unknownbrackets/softgpu-lighting 
softgpu: Precompute lighting parameters
 2022-01-17 01:06:35 +01:00
Unknown W. Brackets 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.

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