2019-07-15gl_shader_cache: Address CI issuesReinUsesLisp1-2/+1
2019-07-15gl_rasterizer: Implement compute shadersReinUsesLisp1-11/+27
2019-07-09shader_ir: propagate shader size to the IRFernando Sahmkow1-4/+4
2019-06-03gl_shader_decompiler: Remove guest "position" varyingReinUsesLisp1-17/+2
"position" was being written but not read anywhere besides geometry shaders, where it had the same value as gl_Position. This commit replaces "position" with gl_Position, reducing the complexity of our code and the emitted GLSL code.
2019-05-30gl_rasterizer: Move alpha testing to the OpenGL pipelineReinUsesLisp1-27/+0
Removes the alpha testing code from each fragment shader invocation.
2019-05-27gl_shader_gen: Always declare extensions after the version declarationReinUsesLisp1-6/+3
This addresses a bug on geometry shaders where code was being written before all #extension declarations were done. Ref to #2523
2019-05-19gl_shader_gen: std::move objects where applicableLioncash1-7/+7
Avoids performing copies into the pair being returned. Instead, we can just move the resources into the pair, avoiding the need to make copies of both the std::string and ShaderEntries struct.
2019-04-20Apply Position Y DirectionFernando Sahmkow1-0/+3
2019-04-14gl_shader_decompiler: Use variable AOFFI on supported hardwareReinUsesLisp1-7/+8
2019-04-04video_core/renderer_opengl: Remove unnecessary includesLioncash1-1/+0
Quite a few unused includes have built up over time, particularly on core/memory.h. Removing these includes means the source files including those files will no longer need to be rebuilt if they're changed, making compilation slightly faster in this scenario.

2018-11-10gl_shader_decompiler: Guard out of bound geometry shader input readsReinUsesLisp1-2/+2
Geometry shaders follow a pattern that results in out of bound reads. This pattern is: - VSETP to predicate - Use that predicate to conditionally set a register a big number - Use the register to access geometry shaders At the time of writing this commit I don't know what's the intent of this number. Some drivers argue about these out of bound reads. To avoid this issue, input reads are guarded limiting reads to the highest posible vertex input of the current topology (e.g. points to 1 and triangles to 3).
2018-10-30global: Use std::optional instead of boost::optional (#1578)Frederic L1-4/+4
* get rid of boost::optional * Remove optional references * Use std::reference_wrapper for optional references * Fix clang format * Fix clang format part 2 * Adressed feedback * Fix clang format and MacOS build

2018-10-22Use standard UBO and fix/stylize the codeFernandoS271-1/+28
2018-10-20gl_shader_decompiler: Move position varying declaration back to gl_shader_genReinUsesLisp1-0/+7
The intention of declaring them in gl_shader_decompiler was to be able to use blocks to implement geometry shaders. But that wasn't needed in the end and it caused issues when both vertex stages were being used, resulting in a redeclaration of "position".
2018-10-07gl_shader_decompiler: Implement geometry shadersReinUsesLisp1-25/+59
2018-09-11Fixed renderdoc input/output textures not working due to render targetsDavid Marcec1-1/+8
2018-09-06gl_shader_gen: Initialize position.Markus Wick1-0/+1
IMO the old code is fine, but nvidia raises shader compiler warnings. Trivial fix through...
2018-08-28renderer_opengl: Implement a new shader cache.bunnei1-2/+2
2018-08-22renderer_opengl: Namespace OpenGL codeLioncash1-2/+2
Namespaces all OpenGL code under the OpenGL namespace. Prevents polluting the global namespace and allows clear distinction between other renderers' code in the future.
2018-08-21Shaders: Write all the enabled color outputs when a fragment shader exits.Subv1-1/+1
We were only writing to the first render target before. Note that this is only the GLSL side of the implementation, supporting multiple render targets requires more changes in the OpenGL renderer. Dual Source blending is not implemented and stuff that uses it might not work at all.
2018-08-15Rasterizer: Implemented instanced rendering.Subv1-0/+2
We keep track of the current instance and update an uniform in the shaders to let them know which instance they are. Instanced vertex arrays are not yet implemented.
2018-07-13gl_shader_gen: Implement dual vertex shader mode.bunnei1-9/+35
- When VertexA shader stage is enabled, we combine with VertexB program to make a single Vertex Shader stage.
2018-06-16gl_shader_gen: Set position.w to 1.bunnei1-0/+4
2018-06-06GPU: Implement sampling multiple textures in the generated glsl shaders.Subv1-2/+0
All tested games that use a single texture show no regression. Only Texture2D textures are supported right now, each shader gets its own "tex_fs/vs/gs" sampler array to maintain independent textures between shader stages, the textures themselves are reused if possible.
2018-04-18gl_shader_gen: Support vertical/horizontal viewport flipping. (#347)bunnei1-0/+10
* gl_shader_gen: Support vertical/horizontal viewport flipping. * fixup! gl_shader_gen: Support vertical/horizontal viewport flipping.

2017-05-27OpenGL: Improve accuracy of quaternion interpolationYuri Kunde Schlesner1-3/+5
Current order of operations (rotate then normalize) seems to produce a lot more distortion than normalizing and then rotating. This makes Citra results match pretty closesly with hardware, and indicates that hardware may also be using lerp instead of slerp to interpolate the quaternions.

2016-02-05renderer_opengl: Use textures for fragment shader LUTs instead of UBOs.bunnei1-11/+7
- Gets us LUT interpolation for free. - Some older Intel GPU drivers did not support the big UBOs needed to store the LUTs.

2015-12-01PICA: Properly emulate 1-stage delay in the combiner bufferYuri Kunde Schlesner1-7/+11
This was discovered and verified by @fincs. The tev combiner buffer actually lags behind by one stage, meaning stage 1 reads the initial color, stage 2 reads stage 0's output, and so on. Fixes character portraits in Fire Emblem: Awakening and world textures in Zelda: ALBW. Closes #1140.
2015-11-26renderer_opengl: Fix uniform issues introduced with kemenaran/avoid-explicit-uniform-location.bunnei1-2/+2
2015-11-25Use regular uniform locationPierre de La Morinerie1-5/+1
The support for GL_ARB_explicit_uniform_location is not that good (53% according to http://feedback.wildfiregames.com/report/opengl/feature/GL_ARB_explicit_uniform_location). This fix the shader compilation on Intel HD 4000 (#1222).
