From aaf7b17db047f0cb2630b479d5468062e6ca815e Mon Sep 17 00:00:00 2001 From: Dave Parks Date: Tue, 27 Sep 2022 23:32:02 -0500 Subject: SL-18190 WIP -- Take 2 on linear space windlight (more methodical approach -- make desired interface but brute force color conversions). Placeholder PBR water and move to deprecate forward rendering shaders. --- indra/newview/app_settings/shaders/class2/windlight/skyV.glsl | 2 -- 1 file changed, 2 deletions(-) (limited to 'indra/newview/app_settings/shaders/class2/windlight/skyV.glsl') diff --git a/indra/newview/app_settings/shaders/class2/windlight/skyV.glsl b/indra/newview/app_settings/shaders/class2/windlight/skyV.glsl index a0a33b8642..3edc94f4ca 100644 --- a/indra/newview/app_settings/shaders/class2/windlight/skyV.glsl +++ b/indra/newview/app_settings/shaders/class2/windlight/skyV.glsl @@ -55,8 +55,6 @@ uniform float max_y; uniform vec4 glow; uniform float sun_moon_glow_factor; -uniform vec4 cloud_color; - void main() { // World / view / projection -- cgit v1.2.3 From b6e576c7c2a1cb395092cc66b1836157872b131f Mon Sep 17 00:00:00 2001 From: Dave Parks Date: Tue, 11 Oct 2022 20:20:39 -0500 Subject: SL-18190 Cleanup -- convert some vec4's to vec3's (as they really are), remove some unused glsl files. --- .../shaders/class2/windlight/skyV.glsl | 36 +++++++++++----------- 1 file changed, 18 insertions(+), 18 deletions(-) (limited to 'indra/newview/app_settings/shaders/class2/windlight/skyV.glsl') diff --git a/indra/newview/app_settings/shaders/class2/windlight/skyV.glsl b/indra/newview/app_settings/shaders/class2/windlight/skyV.glsl index 3edc94f4ca..8f7726bb0b 100644 --- a/indra/newview/app_settings/shaders/class2/windlight/skyV.glsl +++ b/indra/newview/app_settings/shaders/class2/windlight/skyV.glsl @@ -32,18 +32,18 @@ ATTRIBUTE vec3 position; /////////////////////////////////////////////////////////////////////////////// // Output parameters -VARYING vec4 vary_HazeColor; +VARYING vec3 vary_HazeColor; // Inputs uniform vec3 camPosLocal; -uniform vec4 lightnorm; -uniform vec4 sunlight_color; -uniform vec4 moonlight_color; +uniform vec3 lightnorm; +uniform vec3 sunlight_color; +uniform vec3 moonlight_color; uniform int sun_up_factor; -uniform vec4 ambient_color; -uniform vec4 blue_horizon; -uniform vec4 blue_density; +uniform vec3 ambient_color; +uniform vec3 blue_horizon; +uniform vec3 blue_density; uniform float haze_horizon; uniform float haze_density; @@ -52,7 +52,7 @@ uniform float density_multiplier; uniform float distance_multiplier; uniform float max_y; -uniform vec4 glow; +uniform vec3 glow; uniform float sun_moon_glow_factor; void main() @@ -81,17 +81,17 @@ void main() float rel_pos_len = length(rel_pos); // Initialize temp variables - vec4 sunlight = (sun_up_factor == 1) ? sunlight_color : moonlight_color; - vec4 light_atten; + vec3 sunlight = (sun_up_factor == 1) ? sunlight_color : moonlight_color; + vec3 light_atten; // Sunlight attenuation effect (hue and brightness) due to atmosphere // this is used later for sunlight modulation at various altitudes - light_atten = (blue_density + vec4(haze_density * 0.25)) * (density_multiplier * max_y); + light_atten = (blue_density + vec3(haze_density * 0.25)) * (density_multiplier * max_y); // Calculate relative weights - vec4 combined_haze = abs(blue_density) + vec4(abs(haze_density)); - vec4 blue_weight = blue_density / combined_haze; - vec4 haze_weight = haze_density / combined_haze; + vec3 combined_haze = abs(blue_density) + vec3(abs(haze_density)); + vec3 blue_weight = blue_density / combined_haze; + vec3 haze_weight = haze_density / combined_haze; // Compute sunlight from rel_pos & lightnorm (for long rays like sky) float off_axis = 1.0 / max(1e-6, max(0., rel_pos_norm.y) + lightnorm.y); @@ -119,21 +119,21 @@ void main() // For sun, add to glow.
