Gregory Hainaut c445a14c46 gsdx ogl: extend shader to lookup a single channel 2016-04-28 22:56:38 +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 3f404c8edb gsdx-ogl: update shader pipeline intertace to use vs/gs/ps triplet
Better to have 1 function calls with 3 parameters rather 3 functions call with 1 parameter.

Gregory Hainaut decac5fd12 gsdx ogl: implement an empty BeginScene
Compile will devirtualize it and then remove it during the inline.

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

Jonathan Li cbd2417833 gsdx:ogl:windows: Fix calling convention mismatch
OpenGL does not use the cdecl calling convention (which is the default
calling convention for GSdx on Windows). Since DebugOutputToFile is used
by OpenGL, it needs to use the same calling convention that OpenGL uses.

This fixes a debug build crash when the OpenGL renderers are used and
debug_opengl is nonzero in the ini.

Gregory Hainaut 5fb8c7e65c gsdx: initialize members in constructor of objects
A couple of useless members were removed too.

Also fix wnd initialization

Coverity:

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

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

Gregory Hainaut c7b2f9d1d2 gsdx-ogl: setup fbo to always write to first buffer
GL_NONE was kind of useless because nothing was attached anyway

Gregory Hainaut 61694013a5 gsdx-ogl: compact blending parameter structure
Save 656B of data. It is good for the cache.

Gregory Hainaut df3ade896b gsdx-ogl: use integer for blend factor
Integer argument&comparison might be lighter

Gregory Hainaut 5b57405517 gsdx-ogl: blend management cleanup
* reorder the blend function
* remove OM bsel object
* add a bit to support pabe (miss the glsl part)

Gregory Hainaut 921b22ac31 gsdx-ogl: drop useless parameter of OMSetDepthStencilState 2015-08-05 22:55:12 +02:00
Gregory Hainaut b7e16b5989 gsdx-ogl: clean the blending management
Intially GSBlendStateOGL was an alias of the m_blendMapD3D9 array

The object was replaced by an index in the array. Save 2k of memory duplication.
And too much useless code.

v2: push/pop blending state in DATE stuff
v3: remove m_state which is useless now

Gregory Hainaut 744f9ebc09 gsdx-ogl: rare corner case when both texture shuffle and date are enabled
In texture shuffle mode the texture data is either RG or BA. It means
that DATE must either checks MSB of G or A.

Gregory Hainaut 97b38d9e1b gsdx-ogl: directly set impossible mode in the blending table
Avoid to hack it in the creation

Allow in the future to reuse the table directly instead of converting
in a blend object

Gregory Hainaut 8554f32086 gsdx-ogl: clean the blend table

Gregory Hainaut 93c47feb7c gsdx-ogl: replace old colclip algo with the HDR algo
Similar speed but more accurate

Allow to clean the code
2015-07-31 09:45:28 +02:00
Gregory Hainaut 83f874db93 gsdx-ogl: remove bsel.ps
Just clear bsel.abe to disable blending

Gregory Hainaut 83dfc6b633 gsdx-ogl: clean a bit selector code
Use countof macro (avoid to duplicate the size)
Fix the size of array
Remove useless alpha_stencil case
2015-07-30 18:36:05 +02:00
Gregory Hainaut e026f1bac6 gsdx-ogl: implement a fast accurate colclip algo
The idea is to use a floating texture to accumulate the data and
then do a final postprocessing pass to apply the modulo

v2:
* use bounding box to
* fix vertex corruption issue
* use negative number in shader which allow to use half float (+12
  fps@4x)

Gregory Hainaut ee9edb0b19 gsdx-ogl: create a copy rect with conversion function
Previous CopyRect function does a memcopy without conversion.

This function will allow to use different format for input/output. Just a
possibility for the future
2015-07-30 18:22:59 +02:00
Gregory Hainaut ae8df002af gsdx-ogl: optimize Cs * As + Cd and Cs * Af + Cd blending
Basically the code does the alpha multiplication in the shader therefore
the blend unit only does a pure addition. This way the multiplication is
accurate and accurate_blending doesn't requires a costly barrier.

This code also avoid variable duplication to make the code more separated.
Hopefully blending can be done in a separated function

It is preliminary work to support fast color clipping with HDR

v2: fix assertion compilation failure

v3: fix regression in not accurate mode

v3: Cs * As/Af is not an accumulation

Those cases don't need the Cd addition and were already optimized anyway

Fix a regression on GoW2

Gregory Hainaut 5c740ff41e gsdx-ogl: wipeout AlphaStencil & Alpha hack
Accurate options do a better jobs. Technically it can still
be useful for old gpu/driver that doesn't support the GL4.5 extension.

On Windows, you can still rely on Dx

On linux, free driver support it (except Intel)
2015-07-19 22:43:48 +02:00
Gregory Hainaut b4c04ed00a gsdx-ogl: wipeout subroutine code
Code was completey bitrotten
Code was a partial test (and yet 500 lines already)
Shader is more and more complex and multithreading support greatly
reduce the cost of shader switch
2015-07-17 21:08:49 +02:00
Gregory Hainaut 784822a5c2 glsl: redo blending management to use A/B/C/D directly
1/ Code is much more readable
2/ It will allow to round differently the operation in the future

Gregory Hainaut e245b27c97 gsdx-ogl-debug: allow to dump various ps shader
Nvidia allows to get the ASM of the shader of the compiled shader. It is useful
to check the performance.

It also allow me to compile most of shader code path for QA

Dump is enabled in linux replayer + debug_glsl_shader = 2

Gregory Hainaut 2ccf108534 gsdx-ogl: add back a selector for the Geometry Shader 2015-07-11 14:35:34 +02:00
Gregory Hainaut 6121677aa1 gsdx-tc: use a single shader pass to convert texture in 8 bits format
It might save a couple of fps

Add a define to test the perf if we keep only the blue channel. It brokes
the code in Prince Of Persia that use the Red/Green channel... Maybe the
speed hack :( Or find a way to replace all if with a lookup table

Note: it is only supported on OpenGL currently

Gregory Hainaut d29e375f72 gsdx-tc: GPU accelerate 8 bits texture conversion
Only native is supported currently

Gregory Hainaut 839003467e gsdx-ogl: add support of partial frame buffer masking
It might help to fix a bit the color on a couple of games

accurate_fbmask = 1

Code uses GL4.5 extensions. So far it seems the effect is ony used a couple
of time and often in non-overlapping primitive. Speed impact will likely remain small

Gregory Hainaut 42e911c78f gsdx-ogl: mask alpha channel in depth conversion
Might not work if depth is recasted as a rt (we lost the alpha channel)
2015-07-01 09:30:20 +02:00
Gregory Hainaut 58ce7d4bb8 gsdx-ogl: emulate texture shuffle
GS doesn't supports texture shuffle/swizzle so it is emulated in a
complex way.

The idea is to read/write the 32 bits color format as a 16 bit format.
This way, RG (16 lsb bits) or BA (16 msb bits) can be read or written with
square texture that targets pixels 1-8 or pixels 8-16.
However shuffle is limited. For example you can copy the green channel
to either the alpha channel or another green channel.

Note: Partial masking of channel is not yet implemented

V2: improve logging
V3: better support of green channel in shader
V4: improve detection of destination (issue due to rounding)

Gregory Hainaut 5bf5b5bca4 gsdx-ogl: extend StretchRect to write in depth texture
It will allow to convert color texture to depth texture
