- 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.
- there was a case where setting a clear color on the Renderer
would clear a blended view with that color instead of transparent
pixels.
- move configuring the ui view into ImGuiHelper
- fix gltf_viewer sidebar so its background is not uninitialized
* API BREAKAGE: this change aims to fix multi-view support
What has changed:
- View doesn't have a notion of clear color anymore
- View doesn't have a notion of discard flags anymore
- The clear color and color-buffer discard/clear flags are moved to Renderer
- Skybox can now be set to a constant color
- View have a blend-mode
What does is all mean:
"Clearing" (i.e.) setting its background is now handled by Skybox, by
setting a constant color to the Skybox. This should take care of
drawing views side by side.
When a view needs to be drawn on top of another, it's BlendMode needs to
be set to TRANSLUCENT and of course and, generally, it wither won't have
a skybox, or will have one that sets some translucent pixels.
As an optimization, a View with BlendMode::OPAQUE will have its
background cleared with the color specified in Renderer.
If the SwapChain already has some content, it's now possible to set
the Renderer to not discard the content, together with TRANSLUCENT views,
it's possible to draw on top of that content.
It is NOT possible to share depth/stencil buffers between views.
Fixes: #2369, #2372, #2364
* Address reviewers comments.
Note: WebGL is still broken with this PR
* 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
