Rohit Nirmal f15c142c5e Silence some -Wsign-compare warnings. 2015-04-09 18:55:01 -05:00
Subv 1248e291f0 GPU: Added the stencil test structure to the Pica Regs struct. 2015-03-09 20:13:21 -05:00
Subv 414b0741c4 GPU: Implemented more depth buffer formats.

bunnei 34c31db14a GPU: Added RGB565/RGB8 framebuffer support and various cleanups.
- Centralizes color format encode/decode functions.
- Fixes endianness issues.
- Implements remaining framebuffer formats in the debugger.

archshift 7f9ee69a2b Added RGBA5551 compatibility in the rasterizer
This allows Virtual Console games to display properly.
2015-02-27 19:15:08 -08:00
Subv c564c21668 GPU: Implemented bits 3 and 1 from the display transfer flags.
Bit 3 is used to specify a raw copy, where no processing is done to the data, seems to behave exactly as a DMA.
Bit 1 is used to specify whether to convert from a tiled format to a linear format or viceversa.

Subv 5410367ebf Rasterizer: Fixed a warning in GetWrappedTexCoord.
Redeclaring the variable inside the switch was causing weird behavior.

Tony Wasserka e11fb96408 Pica/TextureEnvironment: Treat texture combiner source 1 as the PrimaryColor.
Not really sure where the difference is, but some applications seem to use this 1:1 the same way...

Tony Wasserka 638b370fb5 Pica/Rasterizer: Clean up and fix backface culling. 2015-02-18 14:50:28 +01:00
Tony Wasserka 365236fa4c Pica: Cleanup clipping code and change screenspace z to range from -1..0.
The change in depth range seems to reflect better to what applications are expecting, and makes for cleaner code overall (hence is more likely to reflect hardware behavior).

Darius Goad 5db62cc758 Fix Min and Max blend equations 2015-02-11 15:33:44 -06:00
archshift ef24e72b26 Asserts: break/crash program, fit to style guide; log.h->assert.h
Involves making asserts use printf instead of the log functions (log functions are asynchronous and, as such, the log won't be printed in time)
As such, the log type argument was removed (printf obviously can't use it, and it's made obsolete by the file and line printing)

Also removed some GEKKO cruft.

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.

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 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.
