The most recently loaded model is now automatically re-loaded if you
re-start the sampler-gltf-viewer app.
Super useful in my case for `rgb-lights.glb` :)
This adds support for decoding HDR files, dropping them into the remote
web page, and sending them over the wire. However the decoded results
are not yet passed into IBLPrefilterContext, that will be subsequent
PR.
Rename KtxLoader to KTXLoader.
The remote UI has been tweaked a bit, so that it shows a more helpful
message when disconnected.
Just for fun, this is an example of a web component that allows you to
embed a Filament viewer with a single HTML element. It does not have
many features, but is much easier to use than our raw JavaScript API.
This regressed when we added a callback argument, because the callback
cannot be bound.
This commit also modifies the helmet example to use the low-level API
for testing purposes.
Note that this omits the optional nanoseconds argument. JavaScript
does not support overloading and this argument probably cannot be
accurately provided anyway in a web environment.
Fixes#3002.
In retrospect, I should've exposed ints to JS instead of entities.
Making this fix is already a TODO, but it will be a tedious change. For
now, this PR fixes two issues that were causing tiny but frequent memory
leaks, according to the emscripten memory leak widget.
(1) Do not include Entity in the list of classes that should only be
passed around by pointer.
(2) Clients should always call delete() on returned Entities.
This example has fallen out of date, I tried to resurrect it but it
turned out to be non-trivial, given the special nature of emscripten's
generated JavaScript wrappers.
It might be better to provide an example that uses rollup, since that's
the bundler that model-viewer uses, or a simple TypeScript example.
For now, I think our simple HTML + raw JS samples are sufficient.
This repairs the `animation.html` sample. Using a JS array is more
natural for web developers and more consistent with the latest
JavaScript bindings in gltfio.
-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.
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.
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.
