* Add #include preprocessing to filamat and matc
* Update RELEASE_NOTES
* Fix RELEASE_NOTES
* Use final instead of virtual / override
* Clarify comments
* Use pure virtual for includer functions
* Use a callback instead of an interface
* Rename Includer.h to IncludeCallback.h
* Update comment
This enhances the exisiting matc option "--debug" so that it includes
debug information in the resulting SPIR-V.
Previously we tied this to the build configuration which isn't very
flexible. Moreover this needs to be orthogonal to shader opts, because
we often need to debug problems that arise from optimization.
This CL also gives meaningful names to the ubershader materials and
fixes up the new matinfo analysis so that it prints the entire SPIRV
chunk that corresponds to each potentially problematic GLSL codeline.
Motivated by #1516.
This works by aliasing CUSTOM0 - CUSTOM7 to morphing attributes, and by
extending our existing skinning variant.
This PR was tested against some upcoming changes to gltfio.
Issue #1149, #1417
This is a prep step for the upcoming morph feature and does not require
a bump to our material version number.
Stay tuned for a new sample app that demonstrates this feature.
* 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).
(1) Merge two same-sized lists into a single map with struct values.
(2) Constify all the string-to-enum maps and move them into the
scope where they are used.
(3) Move a bunch of object methods into static free functions to
simplify the header and reduce code duplication.
(4) The PARAM_KEY_FOO string constants were referenced only once (except
in a few error messages) so replace them with string literals.
* 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
* 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
In this first step, we just "blindly" move everything under src/driver
to a new library libbackend.a. And all headers are moved under
private/backend.
Note that "driver" is renamed "backend", but namespaces are unchanged for now.
Later we'll have to untangle the actual private headers from public
ones and ideally not have any private headers.
Material archives already contain two version chunks (post process and
normal) but the renderer was ignoring these. The change makes it so that
matc writes a new MaterialEnums value into these chunks, and the engine
panics when receiving a material version that it does not expect.
This also adds a --version option to matc. No changes were necessary
to matinfo because it already prints out these values.
Fixes#796.
* 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
* Enable optimization passes on materials with external samplers
Because external samplers are not properly supported by SPIRV and
associated library (spirv-cross and spirv-tools) we currently disable
all optimizations when we encounter a material with external samplers.
This however causes issues on some misbehaved drivers (not running
the optimizations has a side effect which causes a crash). To enable
the optimization pass we simply rely on the Vulkan codegen target to
substitute samplerExternal with sampler2D. We then analyze the output
GLSL (post-optimization) and revert the relevants sampler2D declarations
to samplerExternal declarations.
This fixup only occurs after optimization and for mobile targets and
if external samplers were declared.
* Address review comments
- move UBO declarations in UibGenerator, i.e. next
to their Uniform Interface Block definition.
This should help forgetting to update one but
not the other.
- move UniformInterfaceBlock.h and SamplerInferfaceBlock.h under
private/filament/.
- do the same things for samplers
* Exclude comments from brace parsing in vertex/fragment blocks
If a comment contained an opening brace { but not the matching
closing one, matc would not count braces properly and not find
the proper end of a vertex/fragment block.
* Add test
* 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
* Update SPIRV libraries
- Update `spirv-cross`
- Update `spirv-tools`
- Update `glslang`
`spirv-tools` contains a fix for an issue we reported (unnecessary promotions to highp in certain expressions).
* Add SPIRV-Tools dependency to matinfo
* Fix post-process shader when not in Vulkan
The post-process shader must not flip the source texture when we compile for OpenGL. This happens because we use SPIR-V/Vulkan as an intermediate format.
* Fix the Android build
We need to output a location when targeting SPIR-V for mobile.
