-DFILAMENT_SKIP_SAMPLES=ON with CMake
-Pfilament_skip_samples with gradle
This change also renames CMake options specific to Filament
to avoid clashes with subprojects.
After the native async functionality landed, there was no way for web
clients to be notified that the decoding has finished. This PR changes
the existing `onDone` callback so that it gets called after all textures
have been decoded. (Previously it was called after downloading rather
than decoding.)
This has the side effect of simplifying the API because clients no
longer need to call a finalize function.
math/mathwfd.h forward declares all {mat|vec}{2|3|4}<> classes,
which allows us to remove their respective #include in a lot of
our public headers.
Our math headers are full of templates, so this should help build times
a bit.
Also we want to keep the public headers as minimalist as possible.
Note that libgeometry is already included in `filament-android`, this
simply exposes more of its existing functionality.
The Java version of SurfaceOrientation is similar to the JavaScript
version because we are bundling it into the main Filament package, even
though it is a separate library in C++. This is much simpler than
creating a brand new Java package.
New Android sample that tests this is forthcoming.
Fixes#1729.
Fulfills a request from tirichards@.
This is similar in some ways to dynamic backface culling but simpler
because there is no interaction with double-sided lighting.
For reference, dynamic backface culling was implemented with #1936, #1877, #1641.
This feature adds one new method to `FilamentAsset` and uses it in our
Kotlin, JavaScript, and C++ helpers:
utils::Entity popRenderable() noexcept;
This pops a ready renderable off an internal queue, or returns 0 if no
renderables have become ready. It provides a simple way for clients to
gradually add renderables to the scene as they become ready. Previously
clients could only get the entire list of entities, regardless of
whether they had Renderable components or complete textures.
To facilitate this feature, this PR adds a new internal-only class to
gltfio called `DependencyGraph`, which is a temporary object used for
bookkeeping during the asynchronous load.
`DependencyGraph` discovers ready-to-render entities by tracking the
textures that each entity depends on. This is a graph because
renderables connect to a set of material instances, which in turn
connect to a set of parameter names, which in turn connect to a set of
texture objects. These relationships are not easily inspectable using
the Filament API or ECS.
We were already using jobs for decoding PNG and JPEG files, but we were
doing a join. This add three methods to ResourceLoader that allow
clients to amortize the decoding process across multiple frames, even on
single-threaded platforms like WebGL.
This PR adds async loading to the following demos:
- samples/gltf_viewer (now shows a progress bar in the UI)
- android/sample-gltf-viewer
- web/samples/helmet.html
Fixes#1876.
Replace with forward declarations if needed and includes in .cpp that
now need them.
The idea here is to have our headers have the least amount of impact as
possible on our clients (e.g. compilation time).
With KTX, we should simply create the specified output folder and put
the KTX file(s) in there. There is no need to create a subfolder of the
output folder.
This change also allows users to pick a custom name for their KTX file,
because we only use the "deployment" name when generating filenames.
In PR #1906 we enabled depth for all backends, but we forgot web.
Note that this required 0 new codelines whereas Vulkan required 116
additional codelines. :)
Unfortunately we require RTTI to be disabled for web builds
due to the way in which we handle array buffers. This may change
in the future but for now I think it's an acceptable constraint,
especially given the fact that RTTI adds bloat anyway.
