* Add ground shadow option to gltf_viewer
The shadow is always positioned at the bottom of the loaded object's
bounding box to ground it perfectly.
* Remove unused include
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.
This removes the samples/envs folder and replaces these KTX files with a
build step that is driven by CMake / gradle / bash, depending on
platform.
This makes it easier to use IBL files that are generated by the latest
and greatest version of cmake.
The cgltf "base path" that gets passed to cgltf_load_buffers should
actually be the path to original glTF file, otherwise bin filepaths
are resolved incorrectly.
The new gltf_viewer app has an optional zero-arguments mode whereby it
loads a resgen-embedded binary model, which is useful for quick
sanity testing. If you don't specify an IBL, it loads a compressed
version of the pillars IBL.
* Revert "Rollback MeshAssimp enhancements."
This reverts commit b3dce967eb.
* Re-enable glTF support
* Start looking for texture ids at 1, not 0
* Detect if the importer is glTF
* glTF and regular materials both work
