Gregory Hainaut e4337b6631 glsl2h: add input files in the header
Close #1404

Gregory Hainaut 1fb2c66a21 gsdx ogl: Unscale line
Line thickness will be increased to N pixels (N is the upscaling factor).

Code will also be enabled by UserHacks_unscale_point_line = 1

Gregory Hainaut 018895067b gsdx ogl: restore code to unscale point
enabled by UserHacks_unscale_point_line = 1

Point will be transformed into a NxN square sprite. (N is the upscaling factor)

Gregory Hainaut 74822d6ba3 gsdx ogl: rework atst handling
* Move the rounding operation in the constant buffer
* Merge less with less equal. And merge greater with greater equal

Need test

Gregory Hainaut 2b00447a43 glsl: optimize the number of active constant buffer
Increase the performance on the free driver (Nouveau)

Currently the driver validates all UBO when only 1 is updated. It
is clearly a bad idea to put all UBO in a single common headers.

Gregory Hainaut 5d49a6b685 gsdx ogl: replace 4 VS shader variation by an AND mask
Perf will be roughly the same. However there is a single VS for all
the HW emulation.

Gregory Hainaut 959abe64f8 gsdx ogl: implement wildhack on the CPU
Speed impact is likely small and the plan is only to keep a single Vertex Shader

Gregory Hainaut 564bf8a089 gsdx ogl: terminator 3 supports sampling from the depth 2016-05-30 19:39:52 +02:00
Gregory Hainaut fb26254fbb gsdx ogl: implement a more generic HLE shader for terminator 3
Hopefully without regression for others games
2016-05-29 10:13:43 +02:00
Gregory Hainaut f7ddd488e1 gsdx ogl: Extend uniform buffer with channel parameter
Instead to use the standard ps ubo which is used every draw call.
I reused a barely used buffer to reduce the extra cost of the upload
2016-05-29 10:13:43 +02:00
Gregory Hainaut a7ba779ba8 gsdx ogl: another HLE channel effect for terminator 3
Same as before but with a different fbmask value (I don't know why but
I have the feeling that I might need the others value too)
2016-05-20 19:55:39 +02:00
Gregory Hainaut 1c21ea955c gsdx ogl: HLE channel effect for terminator 3
Unfortunately I think the game uses another similar effects
2016-05-20 19:45:20 +02:00
Gregory Hainaut d41613c46a gsdx ogl: add a Tales of Abyss HLE shader
Again fast and efficient but it relies on CRC

v2: forget to update the precompiled shader...

Gregory Hainaut d5681ba01c glsl: fix a bug in urban chaos hle shader
Bug only impact the lsb bits of the depth conversion, so impact is likely small
2016-05-07 22:46:41 +02:00
Gregory Hainaut 70ee8c5bc4 gsdx ogl: add an HLE brightness/contrast shader for GT series.
It works and it is very fast. But it relies on CRC

Others effect need to be tested as well

Gregory Hainaut 7c430c9d3c glsl: fix coordinate in channel depth effect
UV can't be used directly in channel effect

Properly fix Urban Chaos smoke
2016-05-04 18:08:40 +02:00
Gregory Hainaut 5676acaef9 glsl: support channel effect on depth texture too 2016-04-30 16:07:45 +02:00
Gregory Hainaut 14e1ed06df glsl: add an HLE shader for Urban Chaos
Pro:
* Replace 140 draw calls into a single one
* No complex texture conversion/lookup
* smaller solution than a generic solution

Gregory Hainaut 7a5e1d4154 gsdx ogl: allow to use a separate texture for the channel effect 2016-04-29 17:34:17 +02:00

And regression on various games
2016-04-27 09:52:35 +02:00
Gregory Hainaut fda511a949 gsdx glsl: extend hw shader to sample depth texture
Will use integral coordinate to avoid any rescaling.

Bilinear interpolation isn't supported. I don't think it is allowed to
filter a depth texture anyway.

Gregory Hainaut d610a6aac4 gsdx glsl: ofc forget to do the shader in bin 2016-04-24 11:07:46 +02:00
Gregory Hainaut 1558220f74 gsdx glsl: create a common header definition
* avoid duplication between all the files for UBO
* remove various interface define

Gregory Hainaut 12443da00c GSdx ogl: ouch the typo exp != exp2

Gregory Hainaut bc73195193 gsdx-ogl: pack more tightly the FS UBO
Merge TA vec2 + Af vec1 into a single vec4

Gregory Hainaut 9ba470fc63 gsdx-ogl: properly handle t_float in GS
f8c442cf76 misses the swap of t_float in GS

Fix regression in Okami

Bonus: factorize VS_WILDHACK in the VS
2016-02-21 11:48:30 +01:00
Gregory Hainaut f8c442cf76 gsdx-ogl: make VS more generic
Texture coordinate could be dummy/float/int integral/int normalized.

Old behavior:
* VS was in charge to select the texture coordinate
* int integral format wasn't supported

New behavior:
* Always compute all formats
* FS will be in charge to select the good format

Impact:
* VS will be slightly slower but it reduces shaders permutation from
   little to 0 (won't be bad for CPU)
* FS speed isn't impacted as 2 separate code paths were already required
  to support both format
* Rasterizer will be 33% slower but unlikely to be the limited factor of
  the GPU
* In future we could directly use the integral format in the FS.

V2: remove useless PSin_t

Gregory Hainaut b87cda94c5 Merge branch 'glsl-fix-tv-shaders' of git://github.com/turtleli/pcsx2 into turtleli-glsl-fix-tv-shaders 2015-10-25 21:23:39 +01:00
Jonathan Li 1659d5974e gsdx-ogl: Fix scanline, diagonal, triangular TV shaders
PSin.p is normalised, so integer conversions won't work. Use
gl_FragCoord instead.

Gregory Hainaut a8968257db glsl: keep fract in [0;1] range
Shin Megami Tensei Lucifers seems to generate infinites values.
I suspect that DX always clamp fract output.

Finally fix #782 !

Gregory Hainaut 92553add8e gsdx-ogl: accurate date regression. Bad interaction between depth & DATE
In the DATE42 algo, first pass must find the primitive that write the
bad alpha value. If depth test is fail, alpha value won't be written therefore
you mustn't keep the primitive id.

In theory to ensure 100% correctness, depth would need to be fully executed
(currently depth write is disabled). However it requires to copy the depth buffer.
It is likely bad for the perf.

Issue reported on DBZInfWorld

Gregory Hainaut 78569ee833 gsdx-ogl: redo properly the setup of texture format
* add lengthly comment to explain the format
* Likely reduce the number of shader permutation
* Avoid slow AEM (on GPU)

Expect regressions because TC needs some fixes

v2: fix palette mode
2015-09-11 14:14:22 +02:00
Gregory Hainaut ca9b5ce11d gsdx-ogl: move depth conversion shader
Add 2 new shaders:
* ps_main12: cast a 16 bit depth to a RGB5A1 color
* ps_main16: cast a a RGB5A1 color to a 16 bit depth

Shader might be used in future commit as it seems Silent Hill uses this
kind of format.

Fix tab/indentation too

Gregory Hainaut bdc8038e7e glsl: set a size to gl_ClipDistance array
The purpose is to avoid issue on MS-Intel driver without
a dedicated hack in the compilation.

Code doesn't use it so I suspect others implement to discard the
statement.

Gregory Hainaut a1957a685d glsl: drop an useless min in FS
GPU will clamp color anyway. It reduces the number of instruction of 25% (4->3)

Gregory Hainaut 7002ff3ec3 gsdx-ogl: move texture scale from vs_cb to fs_cb
It avoid useless update of the vs_cb.

Gregory Hainaut c5a786ed2c gsdx-ogl: remove support WMS/T == 2 in hardware unit
I think behavior was wrong because only first texel coordinate was clamped.

Beside we can't interpolate if AEM isn't yet applied
2015-08-20 23:01:43 +02:00
Gregory Hainaut 78dd957717 gsdx-ogl: use normalized index coordinate for palette texture
In palette mode, 90% of texture accesses are done in 8 bits.
So let's keep this path as light as possible. It reduces GPU load.

Gregory Hainaut 6b84a89b6a gsdx-ogl: remove old ati hack for point sampler
Was never used on openGL

In the future absolute coordinate will be use anyway

Code is completely broken. It doesn't help to improve speed.

Remove 200 lines ;)
