fa80c448ee softgpu: More closely match PSP light rounding. 2022-01-06 21:19:47 -08:00

cba2374abd softgpu: Separate calculation of S/T.
We could probably reuse, but we're not right now and it complicates the
logic.

d98e5bfc97 softgpu: Improve usage of SSE for lighting.
Gives about a 2% improvement in many places.

2f63f9999d GPU: Normalize 0 to 1 always in software lighting.
See #14167.  This seems to be consistent.

4a0109d273 GPU: Treat negative light exp same as 0.
Based on #12507 and some tests, seems like negative exponents are also
fixed to a 1.0f result.

4816bfc1a6 GPU: Skip specular on negative diffuse factor.
This is correct per hardware tests, see #8403.  Note that the PS3 emulator
running PSP HD remasters does not correctly handle this, and applies
specular for negative diffuse factor.

6e46d6c0f9 GPU: Correct powered diffuse with exp=0.
Just to ensure negative factors are handled too, as they are on hardware.

b2d60cb807 SoftGPU: Cleanup lighting code a bit.
Avoid using Length() when Length2() is enough, simplify some things.

986371c633 SoftGPU: Normalize 0,0,0 as 0,0,1 for shade map.
Takes care of #4155 for software rendering.

b2d3058386 SoftGPU: Correct fog for rectangles.
Gods Eater Burst uses fog in its bloom, with rectangles.

1a56466865 SoftGPU: Match GLES lighting better, use floats.
Using floats simplifies things and also makes it faster.

25bc394284 Ignore the material update flag w/o vertex color.
Instead of using materialambient for all of them.

Fixes #3918, and seems to match tests with 3dstudio.
