From dcd8117b85f45886f78a1a2e9756cb1709d6572a Mon Sep 17 00:00:00 2001 From: Geenz Date: Tue, 9 Apr 2019 22:35:40 -0700 Subject: First stab at moving atmospheric var calcs to its own utility shader. Still some work to go here. Largely related to how certain values (i.e., SSAO mix values) are supplied. But so far, so good. --HG-- branch : OPEN-340 --- .../class1/windlight/atmosphericsFuncs.glsl | 116 +++++++++++++++++++++ .../shaders/class2/deferred/softenLightF.glsl | 6 +- indra/newview/llviewershadermgr.cpp | 4 +- 3 files changed, 124 insertions(+), 2 deletions(-) create mode 100644 indra/newview/app_settings/shaders/class1/windlight/atmosphericsFuncs.glsl (limited to 'indra/newview') diff --git a/indra/newview/app_settings/shaders/class1/windlight/atmosphericsFuncs.glsl b/indra/newview/app_settings/shaders/class1/windlight/atmosphericsFuncs.glsl new file mode 100644 index 0000000000..2854fb8139 --- /dev/null +++ b/indra/newview/app_settings/shaders/class1/windlight/atmosphericsFuncs.glsl @@ -0,0 +1,116 @@ +uniform vec4 gamma;

Given that mShaderObjects only ever expects one copy of a given shader object (leading to lots of "shaderV" and "shaderF"), it made having utility shaders a bit more difficult to incorporate. This change makes sure the two are separated. Using this over a multimap largely for readibility. Also, actually, you know, use this functionality. --HG-- branch : OPEN-340 --- .../shaders/class1/deferred/softenLightF.glsl | 6 +- .../class1/windlight/atmosphericsFuncs.glsl | 6 +- .../shaders/class2/deferred/softenLightF.glsl | 2 +- .../shaders/class2/windlight/atmosphericsV.glsl | 128 ++------------------- indra/newview/llviewershadermgr.cpp | 7 +- 5 files changed, 22 insertions(+), 127 deletions(-) (limited to 'indra/newview') diff --git a/indra/newview/app_settings/shaders/class1/deferred/softenLightF.glsl b/indra/newview/app_settings/shaders/class1/deferred/softenLightF.glsl index 4b9e8290dd..c599c14b43 100644 --- a/indra/newview/app_settings/shaders/class1/deferred/softenLightF.glsl +++ b/indra/newview/app_settings/shaders/class1/deferred/softenLightF.glsl @@ -73,6 +73,8 @@ vec3 fullbrightAtmosTransportFrag(vec3 l, vec3 additive, vec3 atten);
