* | gl_shader_gen: Apply default value to gl_PositionReinUsesLisp2019-11-201-0/+1
|/ | | | | | | Nvidia has sane default output values for varyings, but the other vendors don't apply these. To properly emulate this we would have to analyze the shader header. For the time being, apply the same default Nvidia applies so we get the same behaviour on non-Nvidia drivers.
* gl_rasterizer: Emulate viewport flipping with ARB_clip_controlReinUsesLisp2019-11-071-20/+4
| | | | | | | Emulates negative y viewports with ARB_clip_control. This allows us to more easily emulated pipelines with tessellation and/or geometry shader stages. It also avoids corrupting games with transform feedbacks and negative viewports (gl_Position.y was being modified).

| | | | | | | | Removes the alpha testing code from each fragment shader invocation.
* | gl_shader_decompiler: Remove guest "position" varyingReinUsesLisp2019-06-031-17/+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.
* gl_shader_gen: Always declare extensions after the version declarationReinUsesLisp2019-05-271-6/+3
| | | | | This addresses a bug on geometry shaders where code was being written before all #extension declarations were done. Ref to #2523
* gl_shader_gen: std::move objects where applicableLioncash2019-05-191-7/+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.

* video_core/renderer_opengl: Remove unnecessary includesLioncash2019-04-041-1/+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.

* gl_shader_decompiler: Guard out of bound geometry shader input readsReinUsesLisp2018-11-101-2/+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).

* gl_shader_decompiler: Move position varying declaration back to gl_shader_genReinUsesLisp2018-10-201-0/+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".

* gl_shader_gen: Initialize position.Markus Wick2018-09-061-0/+1
| | | | | IMO the old code is fine, but nvidia raises shader compiler warnings. Trivial fix through...
* renderer_opengl: Implement a new shader cache.bunnei2018-08-281-2/+2
|
* renderer_opengl: Namespace OpenGL codeLioncash2018-08-221-2/+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.
* Shaders: Write all the enabled color outputs when a fragment shader exits.Subv2018-08-211-1/+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.
* Rasterizer: Implemented instanced rendering.Subv2018-08-151-0/+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.
* gl_shader_gen: Implement dual vertex shader mode.bunnei2018-07-131-9/+35
| | | | - When VertexA shader stage is enabled, we combine with VertexB program to make a single Vertex Shader stage.

|
* GPU: Implement sampling multiple textures in the generated glsl shaders.Subv2018-06-061-2/+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.

| * | OpenGL: Improve accuracy of quaternion interpolationYuri Kunde Schlesner2017-05-271-3/+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.
