From 6a5ecfdef1949baaf3597e214ad291b6786f0239 Mon Sep 17 00:00:00 2001 From: Juan Linietsky Date: Thu, 13 Aug 2020 22:07:49 -0300 Subject: Restored fog (non volumetric). Uses a simpler and more intuitive implementation based on density. Its less flexible than before, but its easier to get nice results. --- scene/resources/environment.cpp | 235 ++++++--------------- scene/resources/environment.h | 66 ++---- servers/rendering/rasterizer.h | 5 +- .../rasterizer_rd/rasterizer_scene_high_end_rd.cpp | 20 +- .../rasterizer_rd/rasterizer_scene_high_end_rd.h | 10 + .../rasterizer_rd/rasterizer_scene_rd.cpp | 51 +++++ .../rendering/rasterizer_rd/rasterizer_scene_rd.h | 23 +- .../rasterizer_rd/shaders/scene_high_end.glsl | 42 +++- .../rasterizer_rd/shaders/scene_high_end_inc.glsl | 38 +--- servers/rendering/rendering_server_raster.h | 4 +- servers/rendering/rendering_server_wrap_mt.h | 5 +- servers/rendering_server.cpp | 6 +- servers/rendering_server.h | 4 +- 13 files changed, 233 insertions(+), 276 deletions(-) diff --git a/scene/resources/environment.cpp b/scene/resources/environment.cpp index 526d101389..a174c3eebe 100644 --- a/scene/resources/environment.cpp +++ b/scene/resources/environment.cpp @@ -694,150 +694,59 @@ bool Environment::is_fog_enabled() const { return fog_enabled;
