From cb8d51e37e7d630f1ea3dc816b2d5aaab2295bc2 Mon Sep 17 00:00:00 2001 From: Marcos Date: Mon, 26 Nov 2018 20:31:44 -0300 Subject: GPU States: Implement Polygon Offset. This is used in SMO all the time. (#1784) * GPU States: Implement Polygon Offset. This is used in SMO all the time. * Clang Format fixes. * Initialize polygon_offset in the constructor. --- src/video_core/engines/maxwell_3d.h | 30 +++++++++++-- src/video_core/renderer_opengl/gl_rasterizer.cpp | 12 ++++- src/video_core/renderer_opengl/gl_rasterizer.h | 3 ++ src/video_core/renderer_opengl/gl_state.cpp | 57 ++++++++++++++++++++++++ src/video_core/renderer_opengl/gl_state.h | 10 +++++ 5 files changed, 107 insertions(+), 5 deletions(-) diff --git a/src/video_core/engines/maxwell_3d.h b/src/video_core/engines/maxwell_3d.h index 0c403e16a..286cde201 100644 --- a/src/video_core/engines/maxwell_3d.h +++ b/src/video_core/engines/maxwell_3d.h @@ -590,10 +590,18 @@ public: float clear_color[4];
