* TAA improvements
- fix variance + AABB history clipping (we were computing the union
of both AABB instead of the intersection).
- added a setting for the variance parameter
- added a setting for the jitter pattern
- improved some default values
- fixed a few comments
- smaller code tweaks to facilitate future improvements
Material constants (a.k.a: specialization constants) can only be set
during Material creation through Material::Builder.
This change somewhat relaxes that limitation by allowing constants to
be set at runtime on Material directly.
Currently this new API is still private and only supported on FMaterial.
This feature works by invalidating the HwProgram cache of the concerned
Material, causing a shader recompile per variant; so this API is costly
and should be used only for debugging or during app/game configuration.
The TAA material is modified to use constants instead of #defines for
various settings and those are exposed in TaaOptions as well is in
ViewerGui. So with this change all aspects of the TAA material can
be changed at runtime.
This features didn't work well, had a lot of artifacts and generally
wasn't very useful. This kind of effect should be accomplished
differently.
This is an API break because BloomOptions::anamorphism has been removed.
- add a quality option
- remove the ping-pong code, we'll disable for GPU that don't work
instead.
- improve quality by doing a better first downscale
(using a 5x5 gaussian).
- improve performance by using a 9 tap filter instead of 13 for
in most cases
- fix usages of setMinMaxLevels as it resets the base level to "min"
- separate out the settings for bloom, ssao and ssr
- update webgl binaries
- change default bloom resolution to 384 from 360 to have up to 7
mipmap levels vertically
- FogOption::color is now correctly multiplied by the exposure and
environment intensity.
- New option to exclude the skybox from the fog
- better documentation and naming
This basically adds two settings:
- highPrecision at the View level, which controls the bit depth
of the vsm shadow texture used. This affects all shadowmaps.
- elvsm per shadowmap, which enables Exponential Layered VSM.
the main change in the shaders is that we now always output the
"negative" EVSM, even when it's not enabled. If no shadowmap uses
ELVSM, then the texture is stil an RG texture and the calculation is
lost (with some luck culled by the shader compiler), either way it's
not a lot of math and it's done only once per shadow texel.
During the color pass, on the other hand, we compute the "negative"
EVSM only if enabled.
