The focal length slider now works over a remote connection. Also, the
slider for focus distance now controls the value in `ViewerSettings`
(which gets applied to Camera) rather than the value in
`DepthOfFieldOptions` (which is deprecated).
This fixes two different logcat messages that would occur when scrubbing
a slider in the UI:
- "Discarding message, message queue overflow."
- "Downloading model..." would repeat itself needlessly
This adds a WebSockets server to filament-utils-android.
Unlike my first attempt (#3599), this does not use a piping server and
is therefore much faster to use over a LAN. It also has lower user
friction because there is no need to touch a button in the app or
scan a QR code.
This adds libs/viewer to filament-utils-android and provides JNI
bindings for AutomationEngine.
This commit also changes the AutomationEngine to use PPM for screenshots
rather than PNG. The reasoning is that it is wasteful to include stb and
our two image-related libraries just to dump screenshots, especially for
a feature we might not use on Android.
For testing purposes, sample-gltf-viewer reloads the model when the
user double-taps the screen. This operation was causing a buildup of
blank entities in the Scene, because we were merely destroying the
components, not removing them from the Scene.
- Allow JavaScript and Java / Kotlin clients to configure this setting.
- Opt in by default (this was disabled in #2621)
- Optimize large assets like Bistro by iterating through prims only when
the asset actually has skins.
Fixes#2714.
glTF assets are required to provide min/max attributes for POSITION,
so in theory we never need to compute the AABB. However the option is
still there.
This PR also makes it so that Java clients can choose this option,
previously it was hardcoded for all non-native clients.
This removes (rather than deprecates) all public constructors that
take a native pointer without an accompanying Engine.
Most notably, MaterialInstance had a public pointer constructor which
is now package private. This means that FilamentAsset needs an Engine,
so it now takes the one from AssetLoader.
Static JNI lookups were causing issues with multiple libraries.
We now do the lookups when we need them as they are effectively
just hashmap lookups and we do them only in places where the
work we need to perform will be much larger than a simple hash
map lookup anyway.
This chane also manually registers filament-utils JNI bindings
to get rid of unnecessary symboles. We should do the same for
other Filament libraries (the symbols are pretty long and
we now have many of them).
Renderer can now be given a DisplayInfo that contains some
important information about the current display. This will be used
for frame-pacing and dynamic-resolution.
This is most relevant on Android, where we can accurately query these
parameters. Added support for that in our samples.
This also sets the minSDK to 19 (including gltf viewer's), since this is
the version we support. We were cheating before by under-reporting our
minSdk.
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.
