* Add screen and multiply blending modes
This change also fixes a sorting issue: different sorting modes
were sorted in different buckets which is incorrect. We want
to sort only by distance.
* Update release notes and Java API
* Fix build error
This replaces the previous "curvature to roughness" method. Both are related
and rely on the screen space variance of geometric normals but this new
solution offers more control (the screen space variance and the clamping
threshold can be controlled).
* Add new shading model to Filament for specularGlossiness.
This adds a shading model based on KHR_materials_pbrSpecularGlossiness.
The corollary gltfio change will be in an upcoming PR.
* Improve documentation for specular-glossiness
* MaterialInstance now has setMaskThreshold for convenience.
* Materials now support dynamic doubleSided property.
This does not change the format of material packages because they
already have both getDoubleSided() and getDoubleSidedSet().
The only way in which this change could impact existing applications is
that materials that explicity set doubleSided to "false" will now
respect the material's culling mode, rather than forcing it to NONE.
Fixes gltf_viewer with littlest_tokyo in ubershader mode.
Fixes#963.
* JNI for dynamic material properties.
* Add underscore prefix to internal material params.
* Remove un-needed mat info field.
* Add postLightingColor property to materials
This property can be used to modify the color computed in the lighting
passes of the materials. That color is blended with the computed color
according to the postLightingBlending option (add, transparent or opaque).
* Remove test
* Update docs
* Address code review comment
* Switch postLightingColor default blend mode to transparent
* Add specular anti-aliasing properties to materials
curvatureToRoughness
limitOverInterpolation
These techiques were supposed to be enabled by default on
desktop but it turns out they were broken. They must now
be enabled manually on each material instead (and work on
mobile).
* Update docs/Materials.md.html
* Turn on shaders optimization by default
Release builds of Filament only work well with optimize shaders,
turning optimizations on by default will help avoid mismatches.
This change also adds -g to disable all optimizations, for debug
builds.
* Use -g on debug builds
* Use -g on debug builds
* Update tutorial_redball.md to remove matc's -O
* Update tutorial_suzanne.md to remove matc's -O
* Use -g in debug builds
This calculates the modulo of the user time by a given value, using
the high precision user time. This is useful for animations without
having to worry about resetting the time.
THIS CHANGE BREAKS MATERIALS.
This adds getUserTime() in shaders/materials, which returns the time
in second since Renderer::resetUserTime() was called.
Two values are provided, the time in second encoded as a float and
the difference between that and the double value, which together allows
to perform high precision time computation when needed.
This change allows longer running animations in materials. Using only
the float value, give millisecond resolution for more than 4h.
* Add clear coat normal map support
This change allows to set a separate normal map for the clear coat layer of a material.
* Document the new clearCoatNormal property
* Fix typo
