This example has fallen out of date, I tried to resurrect it but it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.
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.
The new way is to follow the instructions at the top of
`web/docs/build.py`.
The option in build.sh has been unused for a while. Invoking Python from
CMake was pointless, especially since I don't want to force other
developers to install a specific version of Python etc.
Since postRun can no longer be set from within the extern post JS, we
now use the promise rather than postRun.
This upgrades emsdk to 1.39.19 (see note in #2800).
This makes the tutorials more consistent with the live demos and lets us
more easily ensure that the tutorials are kept up to date without
errors. In fact it caught an error in the Suzanne tutorial.
Since this affects source rather than served files, this PR is intended
for main. The master branch will be updated in a subsequent PR.
- 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.
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.
* Improve JS API for SurfaceOrientation helper.
Web developers should not be expected to call malloc on the emscripten
heap. This new API is better aligned with how we handle vertex buffers.
Fixes#2702.
* Update web/filament-js/extensions.js

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.
Adding this for completeness, although the feature triggers a known
issue with Chrome's WebGL implementation that emits an error when
source and destination textures of a draw call are the same.
When no name is provided during instance creation, it does NOT inherit
the name of its parent material. This is because instances should be
lightweight and users can already do instance->getMaterial()->getName().
In a subsequent PR, this feature will be exercised and tested via the
gltfio AssetLoader.
Fixes#2485.
This updates the tutorial markdown, fixes up the literate programming
Python script, and updates the web site itself.
The doc build script now uses a Pipfile instead of "requirements.txt",
which I find less frustrating since it does not interfere with other
Python projects on your machine.
Fixes#2483.
* 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
