Stenzek 340ee8fff8 PixelShaderGen: Implement table-based fog range as in software renderer 2018-02-15 22:19:21 +10:00
Jonathan Hamilton ceb1f8c8cb Enable shader_framebuffer_fetch blend path on ubershaders
Tested on a linux Intel Skylake integrated graphics with
blend_func_extended force-disabled, as it's the only platform I have
that doesn't crash with ubershaders and supports fb_fetch

Jonathan Hamilton 8d68adcaf3 Workaround qualcomm driver bug
It seems it doesn't like modifying inout variables in place - so instead
use a temporary for ocol0/ocol1 and only write them once at the end of
the shader

Jonathan Hamilton 29a9ed043b Implement dual-source blending in shader
For some GLES drivers that don't support dual-source blending, but do
support GL_EXT_shader_framebuffer_fetch, this might be useful.

Stenzek efb9759862 LightingShaderGen: Always calculate lighting for both color channels
Cel-damage uses the color from the lighting stage of the vertex pipeline
as texture coordinates, but sets numColorChans to zero.

We now calculate the colors in all cases, but override the color before
writing it from the vertex shader if numColorChans is set to a lower value.

Stenzek b573319f8f D3D: Fix shader compile error with logicop and alpha test enabled 2017-09-07 11:48:01 +10:00
Stenzek 84f8ebd95f VideoBackends: Clear uid bits that are unused for the current backend
Currently, this is only the logic op bit, but this will be extended to
the framebuffer fetch/blend modes. In the future, when/if we move to
VideoCommon pipelines, this state will be part of the pipeline UID
anyway, and we can mask it out in the backend by using a two-level map,
so the shaders/programs are shared.

Stenzek 0622979d3b ShaderGen: Support writing integer colors when logic op is enabled
This is required for D3D to support logic op.

Stenzek 852e30bb8c Ubershaders: Fix 6-bit color truncation not being applied 2017-08-01 00:01:09 +10:00
Stenzek d54ca2a16a PixelShaderGen: Don't include host early z support in UID
Disable it at shader generation time instead. This way the UIDs are
sharable.

Jonathan Hamilton 35caf48d7d Add a workaround for a PowerVR glsl compiler bug
It seems it doesn't like negating arguments for bitops, so suff like
"var <<= (-othervar);"
fails to compile

degasus 6d2827ff6b PixelShader: Drop redundant warning.
This warning was raised both on UID generation and on shader generation.
2016-10-04 10:13:46 +02:00
degasus 083be0832f LightingShader: Drop xfmem usage.
Our shaders must only depend on the UID, not on any global state.
2016-10-04 10:13:46 +02:00
degasus 829fc8f0ad PixelShaderGen: Drop dstAlphaMode constant in shader generation.
It is already stored within the UID.

Stenzek d9c034e8cc ShaderGen: Specify attribute/output locations/bindings explicitly
This also shifts the SSBO index from index 3 to index 0.

Jules Blok da43f9a156 PixelShaderGen: Always divide the texture coordinates by q.
Some games will set q to a different value than 1.0 through
texture matrix manipulations. It seems the console will still
do the division in that case.

Lioncash 14e0b48ae4 VideoCommon: Make API_TYPE an enum class
Allows for forward declarations in most places, which prevents dumping
unrelated VideoCommon.h contents directly into headers.

Scott Mansell d958388617 VideoCommon: Fix some warnings. 2016-06-26 23:10:31 +12:00
Scott Mansell 24e5d21780 Multithreadded Shadergen: Second pass over Pixel Shadergen.
Note: It's not 100% perfect, as some of the GPU capablities leak into the
pixel shader UID.

Currently our UIDs don't get exported, so there is no issue. But someone
might want to fix this in the future.
2016-06-26 16:13:21 +12:00
Scott Mansell 1a831cfc7d Multithreadded Shadergen: Second Pass over vertex/lighting Shadergens
As much as possible, the asserts have been moved out of the GetUID
function. But there are some places where asserts depend on variables
that aren't stored in the shader UID.

Scott Mansell 4969415f38 Remove global refrences from common code.
Bug Fix: Previously vertex shaders and geometery shaders didn't track
         antialaising state in their UIDs, which could cause AA bugs
	 on directx.
