Tony Wasserka 0f49424022 Pica/Rasterizer: Implement backface culling. 2014-12-31 16:32:55 +01:00
Tony Wasserka 3b78af904e Pica/Rasterizer: Textures seem to be laid out flipped vertically. 
Not sure if this is a correct fix. Probably should instead change the decoding logic itself.

Tony Wasserka 632655e292 Pica: Fix A4, IA4 and IA8 texture formats. 
Both IA4 and IA8 had their component order mixed up. Additionally, IA4 used the wrong number of nibbles per texel. A4 skipped every second texel.

Tony Wasserka b7a48c422a Pica/CommandProcessor: Add support for integer uniforms. 2014-12-31 15:33:09 +01:00
Yuri Kunde Schlesner 8369ee5803 Rasterizer: Pre-divide vertex attributes by W 
Execute the division-by-W for perspective-correct interpolation of
values in the clipper, moving them out of the rasterization inner loop.

Yuri Kunde Schlesner fe186d3a59 GPU: Bitwise texture swizzling 
Replace the loop-based texture address swizzling code by a bit-twiddling
implementation, providing a very small speed up. Also simplify
addressing code.
 2014-12-29 02:08:11 -02:00
Yuri Kunde Schlesner 2012e1420f Rasterizer: Common sub-expression elimination 
Move the computation of some values out of loops so that they're not
constantly recalculated even when they don't change.
 2014-12-29 02:08:10 -02:00
Yuri Kunde Schlesner 7e9bc85cc8 Clipper: Compact buffers on each clipping pass 
Use a new buffer management scheme in the clipper that allows using a
bounded minimal amount of buffer space. Even though it copies more data
it is still slightly faster likely due to using less cache.
 2014-12-29 02:08:10 -02:00
Yuri Kunde Schlesner a320d1a5b4 Clipper: Avoid dynamic allocations 
The triangle clipper was allocating its temporary input, output and work
buffers using a std::vector. Since this is a hot path, it's desirable to
use stack allocation instead.

Yuri Kunde Schlesner d151d797b1 Vertex Shader: Zero OutputVertex to avoid denormals 
Unused OutputVertex attributes were being left un-initialized. The
leftover garbage sometimes decoded as floating-point denormalized
values, causing fallbacks to microcode and massive slowdowns in the rest
of the rasterization pipeline even though the results were unused. By
zeroing the structure we ensure these attributes only contain harmless
zeros.
