- UniformBuffer::toBufferDescriptor() now cleans the dirty flags
- SamplerBuffer move ctor and operator now clean the dirty flags of the
moved (source) buffer.
- SamplerBuffer::toCommandStream() can be used to more efficiently copy
a SamplerBuffer into the command stream -- this saves a copy.
- simplified SamplerBuffer's copy and move ctor/operator
- added a few constexpr here and there
This moves our existing VertexBuffer utility into a new "geometry"
library and adds new functionality for computing tangents based on UV's.
The UV-based method comes from Eric Lengyel.
We considered mikktspace (which thankfully has a zlib-style license) but
it would require re-indexing via meshoptimizer and is therefore a bit
heavyweight.
The new library has no dependencies and will add only 7 KB to Filament's
Android aar file.
Fixes#858 and preps for #528.
This is one of those CMake gotchas, we should always use
CMAKE_CURRENT_SOURCE_DIR instead of CMAKE_SOURCE_DIR to allow
Filament to exist as a subproject.
In particular, this was causing the following build error when trying to
build Filament as a nested project.
combine-static-libs.sh: No such file or directory
Fixes#861.
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.
This class will not extend well to glTF so this cordons it off into the
filamesh namespace, which is an already-existing namespace that we use
for the things related to the filamesh file format.
For glTF we might create a new library with its own MeshReader so
this will mitigate confusion.
In the public docs and materials API, Filament "variables" are custom
interpolants (outputs of VS, inputs of FS). However we internally used
"variables" to also refer to built-in VS inputs.
CodeGenerator had a generateVariable method and a generateVariables
method, which did something completely different. :)
This reverts a JobSystem optimization that attempted to avoid signaling
a condition when there was no waiters. Unfortunately, there was a
race that caused the the signaling thread to miss that the waiter flag
was set, thus not signaling.
The engine tries to be smart by using a single vertex shader when
rendering unskinned, non-alpha masked, non-customized materials.
This leads to a lot of issues when laying down the depth prepass.
This change simply gets rid of this optimization (which wasn't
properly profiled anyway). Correctness is more important.
Fixes#645
* 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
Background: with the Vulkan backend, RGB8 textures do
not work (at least not on my hadrware). This makes me unable to run some
examples, because they use normal maps in RGB8 format.
It appears that the following commit addresses the problem by adding a
special command line option to mipgen:
https://github.com/google/filament/commit/8dda07bf2c19f9ebd8ab499ca2c3849d7b1f031f
However, processing normal maps with this option does not work: certain
assertions in the image library fail.
This PR changes these functions in the image library to handle 4-channel
images instead of failing.
* Improves linear to s/rgb
Adds rounding to nearest whole integer, supports copying over an alpha channel for linear to srgb conversion. Code would previously incorrectly apply sRGB conversion to alpha.
* reformatting previous change
Fixes a header usage problem for MSVC, which complains about StaticString not having a constexpr constructor thus making the "make" method not constexpr.
