- -m option now works with "directory_*.png" or just "*.png"
- "color" replaced by "albedo" to mach other places in the source tree
- fixed warnings
- clear the background when IBL is not used
* Calculate view vector without using camera eye position
* Fix compilation error (during parsing the material when a height map is passed in)
* Add SUN light to the scene
* minimal backend support for compute
- added api to dispatch a compute shader
- added api to create and bind a ssbo
- added api to read back a buffer
Only implemented in the gl backend
* Add a backend compute test suite
* basic support for compute shaders in matc
this is still very much work-in-progress.
We're not supporting images nor ssbo for now.
* rename UniformInterfaceBlock to BufferInterfaceBlock
* augment BufferInterfaceBlock to support ssbo features
- add support for std430
- add support for ssbo
- add support for variable-size array
- add support for memory qualifiers
* reformat MaterialBuilder
* material format: move subpasses outside of parameters
subpasses now are their own json property instead of being a
"parameter".
* refactor parameter() methods to match Buffer/SamplerInterfaceBlock
We're just shuffling the arguments.
* add support for buffers in .mat files
* filamat now generates buffer blocks (ssbo)
* take feature level into consideration when optimizing shaders
* don't store the 'uniform binding' chunk for level 2 materials
this includes some refactoring/cleanups of MaterialParser
* matinfo: fixes for compute
- separate subpasses from parameters
- don't attempt to print material properties
We now have an option for evaluating the bent normals from SSAO.
This is used to improve specular AO.
Currently these bent normals are not used for diffuse lighting because
they're "flat" (face normals), which is too distracting.
The bent normal buffer is stored in the SSAO texture, in a separate
layer. This is the first post processing effect that uses 2D array
in order to limit our sampler usage.
This CL also changes how we handle SPECULAR_AO_BENT_NORMALS when
material bent normals are not available: we're now using the "Cones"
algorithm with the regular normal, instead of Lagarde's approximation.
* Stop using members as globals between methods
* Multi-thread shaders generation with JobSystem
* Pass JobSystem to MaterialBuilder::build()
* Fix MeshAssimp to use the new API
* Allow the Java API to pass a job system via Engine
* Update docs
* Apply suggestions from code review

The user can now choose amongst 3 specular AO methods:
- None, specAO is off
- Simple, specAO is inferred from roughness and diffuse AO
- Bent normals, specAO is computed accurately from cone intersections
The last method is more expensive but produces the best results.
This change also fixes a few issues:
- Rename materialRefraction() and materialRefractionType() for
consistency
- Fixes user time in shaders
* Add support for bent normals
Bent normals can be enabled via the bentNormal property of a material.
When specular occlusion is enabled, bent normals improve the quality
of the computation.
* Save a couple of multiplications in bent specular AO
* Add micro-shadowing based on ambient occlusion
* Prevent crash when IBL is turned off
* Apply micro-shadows to baked AO only
* Remove debug code
* Add opacity control
* Fix opacity term
* Switch to micro-shadowing from Chan 2018
