Pica/VertexShader: Fix a bug caused due to incorrect assumptions of consecutive output register tables.

Emmanuel Gil Peyrot 92fd2a1ee3 VideoCore: Add static_cast around expressions where the compiler doesn’t deduce the right type. 2015-03-16 15:14:04 +01:00
Tony Wasserka e4f5ec6272 Pica/VertexShader: Fix a bug caused due to incorrect assumptions of consecutive output register tables. 
We now write create a temporary buffer for output registers and copy all of them to the actual output vertex structure after the shader has run. This is technically not necessary, but it's easier to vectorize in the future.

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.

Yuri Kunde Schlesner ea3c99f3a2 Video core: Fix A4 texture decoding 
It was trying to take the LSB from `coarse_x`, which would always be 0
and thus would always return the same texel from each byte. To add
insult to the injury, the conditional was actually the wrong way around
too.

Fixes blocky text in OoT.
 2015-02-25 23:05:14 -03:00
Yuri Kunde Schlesner 3c50da6fc0 Video core: Fix pixelation/blockiness in textures. 
This was caused during morton decoding by me not masking the bits of
each coordinate before merging them, so the bits from x could set bits
in y if it was >255.

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.

Yuri Kunde Schlesner 5961a2852d GSP: Update framebuffer info on all interrupts 
Hardware testing determined that the GSP processes shared memory
framebuffer update info even when no memory transfer or filling GX
commands are used. They are now updated on every interrupt, which isn't
confirmed correct but matches hardware behaviour more closely.

This also reverts the hack introduced in #404. It made a few games
behave better, but I believe it's incorrect and also breaks other games.

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.

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.
 2014-12-29 02:08:09 -02:00
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.
