From 0639244d856f403cc9bdec5ca927df7a61edd1d8 Mon Sep 17 00:00:00 2001 From: ameerj <52414509+ameerj@users.noreply.github.com> Date: Thu, 4 Mar 2021 14:14:19 -0500 Subject: renderer_opengl: Swizzle BGR textures on copy OpenGL does not natively support BGR internal formats, which causes many BGR textures to render incorrectly, with Red and Blue channels swapped. This commit aims to address this by swizzling the blue and red channels on texture copies when a BGR format is encountered. --- src/video_core/renderer_opengl/util_shaders.h | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) (limited to 'src/video_core/renderer_opengl/util_shaders.h') diff --git a/src/video_core/renderer_opengl/util_shaders.h b/src/video_core/renderer_opengl/util_shaders.h index 7b1d16b09..93b009743 100644 --- a/src/video_core/renderer_opengl/util_shaders.h +++ b/src/video_core/renderer_opengl/util_shaders.h @@ -19,6 +19,22 @@ class ProgramManager; struct ImageBufferMap; +class Bgr565CopyPass { +public: + Bgr565CopyPass() = default; + ~Bgr565CopyPass() = default; + + void Execute(const Image& dst_image, const Image& src_image, + const VideoCommon::ImageCopy& copy); + +private: + [[nodiscard]] bool CopyBufferCreationNeeded(const VideoCommon::ImageCopy& copy); + void CreateNewCopyBuffer(const VideoCommon::ImageCopy& copy, GLenum target, GLuint format); + + OGLBuffer bgr16_pbo; + size_t bgr16_pbo_size{}; +}; + class UtilShaders { public: explicit UtilShaders(ProgramManager& program_manager); @@ -36,6 +52,9 @@ public: void CopyBC4(Image& dst_image, Image& src_image, std::span copies); + void CopyBGR(Image& dst_image, Image& src_image, + std::span copies); + private: ProgramManager& program_manager; @@ -44,7 +63,10 @@ private: OGLProgram block_linear_unswizzle_2d_program; OGLProgram block_linear_unswizzle_3d_program; OGLProgram pitch_unswizzle_program; + OGLProgram copy_bgra_program; OGLProgram copy_bc4_program; + + Bgr565CopyPass bgr_copy_pass; }; GLenum StoreFormat(u32 bytes_per_block); -- cgit v1.2.3
