From c574ab5aa1d3ff81b28ddfbba3818b3ce724aa32 Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Sat, 4 Jul 2020 18:42:10 -0300 Subject: video_core/textures: Add and use SwizzleSliceToVoxel, and minor style changes Change GOB sizes from free-functions to constexpr constants. Add SwizzleSliceToVoxel, a function that swizzles a 2D array of pixels into a 3D texture and use it for 3D copies. --- src/video_core/textures/decoders.h | 38 ++++++++++++++++++++++++++++---------- 1 file changed, 28 insertions(+), 10 deletions(-) (limited to 'src/video_core/textures/decoders.h') diff --git a/src/video_core/textures/decoders.h b/src/video_core/textures/decoders.h index 06f3ebf87..232b696b3 100644 --- a/src/video_core/textures/decoders.h +++ b/src/video_core/textures/decoders.h @@ -10,15 +10,15 @@ namespace Tegra::Texture { -// GOBSize constant.
