2019-02-28EEP performance WIPGraham Linden
Mods to improve alpha obj render performance. Removes hacky fix for HUD elements getting atmospherics. Re-orders rendering of glow to remove ~10ms/frame of shader re-re-rebinding. Fix up default classes and basic shader loading (remove unused shared modules).
2019-02-26Fix ifdef in alphaF.Graham Linden
2019-02-26Fix up ifdefs to make OSX shader compiler happy.Graham Linden
2019-02-26SL-10566 part the firstGraham Linden
Tie using deferred rendering in water reflection/distortion map generation to debug var again (claw back some performance lost to doing post-deferred in water map generation). Edit softenLightF for class1/class2 to make them comparable again.
2019-02-26MergeGraham Linden
2019-02-26SL-5186, SL-10612Graham Linden
Fix lighting and gamma correction differences between deferred and forward rendering including materials objects. Verify 10612 and 10500 remain fixed. Make sure all necessary deferred shaders get the atmospheric uniform updates for doing frag-based atmospherics.
2019-02-25Disable nSight debug by default (breaks snapshots).Graham Linden
2019-02-25SL-9806Graham Linden
Remove fade effect on sun disc as it nears horizon (stars poke through).
2019-02-25SL-9806Graham Linden
Remove blend effect when sun disc nears horizon (was letting the stars show through).
2019-02-22SL-5186Graham Linden
Add ambiance handling to the light loop in the forward incarnation of materialF and tweak alphaF to match lighing of material alpha-blend objects and non-ALM rendering.

2019-02-22SL-10415, SL-10612, SL-10569Graham Linden
Fix shadow sampling min with caster dp and offset tweaks. Fix moon direction not being transformed as the sun dir is. Fix colorspace issue causing some objects to render grayish instead of blackish.

2019-02-14SL-10552Graham Linden
Fix view-dependent peter-panning from incorrectly biased shadow pos offset.
2019-02-13SL-10181, SL-10546Graham Linden
Fix distortion map rendering in deferred mode not including underwater fog effects. Fix distortion map rendering not including post-deferred content at all. Fix distortion map rendering not including anything but sky when camera is underwater. Update sun_up_factor/sunmoon_glow_factor uniforms even when sun disc isn't in use.
2019-02-11SL-10500Graham Linden
Replace clamp on height in atmospherics calcs on fragment shader path. Fix colorspace conversions in material shaders in forward rendering mode. Fix deferred shaders not setting the sun_up_factor uniform and getting moonlight instead of sunlight.
2019-02-08SL-10457Graham Linden
Make area beyond far split of directional light unshadowed again.
2019-02-08SL-10415Graham Linden
Another pass at playing with shadow_offset/bias to balance between peter-panning and shadow acne while sun and/or moon are near the horizon.
2019-02-06SL-10478Graham Linden
Fix side-effects of having both sun and moon as potential directional light contributors. We pass an int to the shader indicating which to prefer instead of making per-pixel decisions and pass the moonlight color/di independently. Obsolete llsettingssky fade color which was unused elsewhere and cached for no reason.
2019-02-06SL-10461Graham Linden
Another attempt at getting approximage handling of projector ambiance in the alpha object shader. This will not be a perfect match for non-transparent objects but should be close enough.
2019-02-04SL-10461Graham Linden
Pass projector ambiance as the .w element of the light_attenuation uniform so that alpha shader can emulate the behavior of proper spot projectors.
2019-02-04SL-10459Graham Linden
Use gl_FragDepth on deferred sun disc to fix z-fighting with sky dome and get layering of sky/stars/sun/moon/clouds correct.
2019-02-01SL-9996, SL-1130, SL-5546Graham Linden
Fix bug with setting texture matrix for rigged mesh. Fix z-fighting between sea and sky in ALM by cheating sky, stars, and moon using gl_FragDepth. Fix handling of atmospheric haze glow w.r.t independent sun/moon positioning (we can no longer depend on them being mutex to each other).
2019-02-01Roll back attempted fix for 9996 on ALM which has unacceptable knock-on effects.Graham Linden
2019-02-01Fix issue with OSX shader compiler not implementing #if correctly (nice job, ↵Graham Linden
Timmy).
2019-01-31Remove (now) unused decodeNormF GLSL shader.Graham Linden
2019-01-319996 partial fix (works for non-ALM rendering only)Graham Linden
Use a new edge water shader to allow forcing frag depth to avoid z-fighting at back edge of water edge pieces. This will not work for ALM because forcing the depth breaks the use of the depth to backproject gbuffer position which breaks lighting calcs.
2019-01-30Eliminate helper GLSL modules depending on further GLSL modules to give ↵Graham Linden
Intel HD x000 compiler a fighting chance. More WIP for edge-specific water shader for 9996.
2019-01-30WIP for 10374 (reduce number of shaders linking against deferredUtil).Graham Linden
Prepare for using ifdef to conditionally engage using gl_FragDepth in water shaders (because GL requires that writing to gl_FragDepth on any path means you need to write a depth value on every path).
2019-01-30SL-9996Graham Linden
Force frag depth in water shaders to avoid z-fighting at back edge of water edge pieces.
2019-01-30SL-10415, SL-10434Graham Linden
Further tweaking of directional shadow sampling to balance between peter-panning and shadow acne. Move stars to just this side of the sky some to reduce parallax. Remove decodeNormF and uses of decode_normal in favor of unified use of getNorm (try to help the Intel HD x000 compiler learn to link correctly).
2019-01-29Roll back fix for 10415 due to knock-on that must needs be tamped down.Graham Linden
2019-01-29SL-10415Graham Linden
Tweak application of shadow bias to balance between shadow acne and Peter-panning by using light_dir z value, per-split bias multiplier, and better jitter noise method. Also tweak impl of spot shadow sampling func to work around issues with Intel HD shader compiler which crashes with Intel HD 3000 driver 4459 due to shadow map array access with index using math (kwality).
2019-01-25SL-10303, SL-10414Graham Linden
Fix positioning of sun/moon discs w.r.t atmo haze glow. Disable killing glow when sun is not up.
2019-01-25SL-10303Graham Linden
Modify sun disc shader to better position itself within the sun glow and to fade as the sun approaches the horizon (to mask where the position difference is greatest).
2019-01-24SL-10276Graham Linden
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.
2019-01-24SL-10281Graham Linden
Use clamp on dot product of view and light norm to eliminate 2nd halo.
2019-01-24SL-10282Graham Linden
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.
2019-01-17SL-10368Graham Linden
Fix OSX shader compile bug from use of #if FOO instead of #ifdef FOO or #if defined(FOO) preventing atmospherics (and thus ALM) from working on OSX.
2019-01-15SL-10369Graham Linden
Fix handling of backfaces in shared shadow sampling broken during de-duplication.
