SL-9851
Fix cloud shaders to ignore clouds when cloud_scale is 0.
Fix creation of heavenly body geo to avoid degenerate vector math
and not randomly flip orientation when crossing zenith.
Add sun_up_factor to eliminate sun glow around moon when sun is down.
|
|
Use clamp on dot product of view and light norm to eliminate 2nd halo.
|
|
Use clamping on dot product to determine halo TCs to fix abrupt cutoff at dot == 0.
Ifdef around engaging advanced atmo which is not ready for primetime yet.

blocks in several shaders).
|
|
atten args.
|
|
De-duplicate ambient occlusion shader code and move to new aoUtil.glsl
Split shared shadow tap funcs into shadowUtil.glsl
|
|
|
|
Modify handling of directional light to prefer sun when it is up but use moon dir/color when it is alone in the sky.
Modify handling of shader in shaders to get some shadowing of ambient and nighttime shadowing.
|
|
Plug more holes through which env ambient terms were finding their way into lighting calcs for HUDs.
Fix up mismatched indenting (tabs v spaces) on several shaders.
|
|
Fix fullbright transport transposed args and use display gamma for post-deferred gamma correction.
|
|
lighting pipe.
|
|
Fix class 1 and 2 transport/gamma funcs and made usage consistent across all shaders.
Fix class1\environment\waterV reverting to old d1/d2 names for wave directions.
|
|
|
|
|
|
Eliminate 20+ callsites with copy-paste of getPosition and/or getNorm code.
Make pipeline use getShadowTarget/releaseShadowTarget consistently.
|
|
lighting shaders.
Also fix terrain response to atmospherics shaders (was failing to apply ambient on low end even when atmospherics was on).
|
|
Make shaders use consistent naming and parameter order for transport and atmospheric helpers.
Share transport and gamma correction code where possible.
Add lots of asserts and other validation for when things don't go as planned.
Engage dumpShaderSource to get more source output with shader compilation fail.
|
|
|
|
|
|
Port over transport, gamma, atmospherics shader stub updates for per-fragment atmospherics.
Fix bindings of current/next noise map when current and next are the same (select only one and force blend factor to 0).
|
|
De-hackify WL additive to get better match between ALM and non-ALM rendering
without bringing back SL-1491 lens flare bug.
|
|
|
|
helper funcs.
|
|
density tab.
Make frag shader version of vert WL shader to include rainbow/halo effect in non-advanced WL sky.
|
|
add cloud_variance control for randomized perturbance of clouds to break up tiling monotony
|
|
between maintaining old look of WL settings and fixing SL1491 lens flare bug
|
|
Modulate class1 softenLight atmospheric additive by specular.a (same fix as for class2).
Clamp additive color to <= vec3(0.2) to avoid similar artifacts in non-deferred render path.
|
|
could be used by HUDs
Make sky and cloud shaders use common scaleSoftClip implementation in gammaF.glsl
|
|
Fix name at top of the 3 softenLight shaders so we can differentiate which is in use when using nSight debug.
Made class2 softenLightF shader modulate the atmospherics additive to only specular shading to fix lens flare on terrain etc.
|
|
Remove moon_dir related shader code causing sunlight shadow artifacting.
|
|
Make env panel update environment when jumping frame to frame.
Add separate funcs for sun/moon vectors in various coord systems.
Make haze glow only pay attention to sun (i.e. fix sun glow when moon is near horizon in daytime).
|
|
shaders to lerp between current and next cloud texture.
|
|
Add plumbing facilities to allow current and next moon textures to be passed to moon shader.
Modify moon shader to blend between current and next moon textures by blend factor.
|
|
coord systems in use.
Fix class2 softenLightF shader.
|
|
Modify autobuild.xml to use new libatmo w/ state save/restore fixes (addresses font render glitch).
Put in nSight debug support.

|

and unify on using the version that works on OSX.
Add more logging to shader loading about fallbacks and loading succcess.
Add frag shaders for sharing sRGB and normal encode/decode via GL shader linkage.

libatmosphere integrated in indra/llrender/llatmosphere.cpp
Still working on runtime shaders to use libatmosphere precomputed atmospherics textures

for less glossy projector reflections.
This makes far more sense than having the “spot” functionality, and opens projectors up to much more practical use cases and fits much better within the concept of glossy reflections than the previous spot behavior.
|
|
|
|
|
|
|
|
This brings projector reflections more in line with the originally intended behavior of environment reflections.
