From c95c254f3eda75476ad221a4828033f4140a3470 Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Fri, 29 May 2020 23:32:41 -0300 Subject: texture_cache: Implement rendering to 3D textures This allows rendering to 3D textures with more than one slice. Applications are allowed to render to more than one slice of a texture using gl_Layer from a VTG shader. This also requires reworking how 3D texture collisions are handled, for now, this commit allows rendering to slices but not to miplevels. When a render target attempts to write to a mipmap, we fallback to the previous implementation (copying or flushing as needed). - Fixes color correction 3D textures on UE4 games (rainbow effects). - Allows Xenoblade games to render to 3D textures directly. --- src/video_core/texture_cache/surface_params.cpp | 17 +++++++++++++---- 1 file changed, 13 insertions(+), 4 deletions(-) (limited to 'src/video_core/texture_cache/surface_params.cpp') diff --git a/src/video_core/texture_cache/surface_params.cpp b/src/video_core/texture_cache/surface_params.cpp index 884fabffe..642eeb850 100644 --- a/src/video_core/texture_cache/surface_params.cpp +++ b/src/video_core/texture_cache/surface_params.cpp @@ -215,10 +215,19 @@ SurfaceParams SurfaceParams::CreateForFramebuffer(Core::System& system, std::siz params.num_levels = 1; params.emulated_levels = 1; - const bool is_layered = config.layers > 1 && params.block_depth == 0; - params.is_layered = is_layered; - params.depth = is_layered ? config.layers.Value() : 1; - params.target = is_layered ?
