We break existing API by returning both the IndirectLight and the
texture. Same thing with Skybox.
Fix one bug where the float array in getSphericalHarmonics wasn't
getting written out.
Fixes#6412
The latest macOS toolchain triggers warnings for duplicate libraries at
link time. This is caused by our dependency chains.
Also remove an inlining warning in Kotlin and unnecessary warnings in
build.sh when doing a clean or generating web docs.
- Use of getter method instead of property access syntax (for getInstance)
- 'rangeTo' or the '..' call should be replaced with 'until' (in for)

Prior to this change, `recomputeBoundingBoxes` was an opt-in config
parameter in ResourceLoader. It is now a method on FilamentInstance.
The old API did not work for dynamically created instances. Since this
is a relatively obscure feature, we considered removing it completely,
especially since the computation requires the presence of CPU-side
vertex data combined with the transform hierarchy.
Instead of removing the feature, we decided to move it to a better
place. This paves the way for some upcoming improvements, which include
reducing the memory footprint for assets. It also improves overall code
organization and separation of concerns.
This change was motivated by some internal work at Google and has the
benefit of simplifying the gltfio API and implementation. There are 2
major API changes:
(1) Consolidate separate loader entry points for GLB and GLTF.
The distinction between GLB and GLTF can be made from the file content
alone, because GLB has a 4-byte magic string in its header. There is no
need for separate entry points. Clients do not (and should not) need
to check the file name extension.
(2) Remove the distinction between "instanced" and "non-instanced"
glTF assets.
In the new scheme, all assets have at least 1 instance.
Broadly speaking, in gltfio an "asset" is a collection of Filament
objects like textures and vertex buffers, while an "instance" is a
collection of entities and components (e.g. the transform hierarchy).
This API change makes life easier for clients because they no longer
need to decide a priori if they will ever need to add instances.
This change also moves some public-facing methods from FilamentAsset to
FilamentInstance:
- getSkinCount, getSkinNameAt
- getJointCountAt, getJointsAt
- attachSkin, detachSkin
auto-instancing can have some overhead, so when it is known that the
scene doesn't have identical primitives, it is better to disable it.
(disabled by default).
Also add some missing bindings for `enableAccurateTranslations`.
This allows clients to provide their own asynchronous texture decoders
for various mime-typed images. This is a plug-in component for gltfio,
in some ways similar to MaterialProvider.
There are two motivations for this: to decouple gltfio from STB and
to make it easier to integrate support for BasisU textures.
This also has the side effect of simplifying ResourceLoader, since the
texture decoding jobs have been moved out.
As part of this work, I made the "stb" CMake target into a traditional
static library. Previously we had several files called `Image.cpp`
whose sole purpose was to enable STB_IMAGE_IMPLEMENTATION.
mipgen can now emit basis-encoded KTX2 files. Both the desktop and
web "suzanne" samples use this as a test for compressed textures.
This PR does not add KTX2 support to glTF, but it's on the way.
`BasisEncoder` has a builder style API that calls the basis encoder to
create KTX2 files. This hides some low-level BasisU features that we are
not using, like file I/O and mipmap generation.
`Ktx2Reader` is an easy-to-use API for creating Filament textures from
KTX2 files. Its API primarily consists of these two methods:
bool requestFormat(Texture::InternalFormat format);
Filament::Texture* load(const uint8_t* data, size_t size);
The first method is used to build an ordered list of formats that are
supported by your hardware. The second method consumes the contents of a
basis-encoded KTX2 file and attempts to produce a Filament texture with
a preferred format.
IMPORTANT: Our tools still let you use KTX1 for non-compressed images
because it is useful for HDR, but you can no longer use KTX1 for
block-compressed data.
Partial fix for #4771.
Changes:
- Remove the strange header-only variant of libs/image
- Rename KtxBundle => Ktx1Bundle
- Move image/KtxUtility => ktxreader/Ktx1Reader
- Add unit test for Ktx1Reader and test stub for KTX2.
Notes:
- Ktx1Bundle does not depend on Filament and is used by cmgen
and mipgen to generate KTX files.
- Ktx1Reader has a dependency on Filament and should therefore live in
a separate library, which it now does.
This is a gltfio API change (!)
Jave clients now need to call destroy on MaterialProvider.
Previously, the Java AssetLoader took over ownership of a native
material provider upon construction, but this was neither documented
nor consistent with the C++ layer. (This is historical; in the past we
did not expose MaterialProvider to Java.)
One motivation for this (aside from API consistency) is that users may
wish to preserve the material cache from one run to another.
Fixes#5132.
The finalizer can't be used to dispose of filament resource, because
it runs on its own thread.
Added a destroy() method to all IBLPrefilter related classes that must
be called once the object is no longer needed.
note: Resources will be freed eventually anyways when the Engine itself is
destroyed.
fixes#4633
This adds some significant JNI glue in order to make the Java API for
gltfio materials much more consistent with C++, and create feature
parity between the two languages.
The motivation is to allow Java clients to provide their own
ubershader-based solution or filamat-based solution.
- The `MaterialProvider` Java class is now an interface.
- The `UbershaderLoader` Java class is now a concrete implementation.
- Users can now write their own provider class using Java / Kotlin.
To streamline the amount of JNI work that occurs at run time, the
MaterialProvider Java interface uses ints in a couple spots instead
of enums. This sacrafices some readability for Java clients who wish
to write their own provider, but makes the JNI much simpler.
This replaces #3975.
The sample would crash when removing `orientation` from `configChanges`
and rotating the device, because the old RemoteServer would still be
alive when creating the second one, so the WebSocket port would be
unavailable.
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.
(1)
The C++ RenderTarget API might be used by an external Android library
such as filament-utils-android and therefore needs to be in the map
file.
(2)
Texture, Skybox, and IndirectLight each had two "nativeObject"
constructors which exist for the benefit of filament-utils-android,
but each of these classes only need one nativeObject constructor.
