- -m option now works with "directory_*.png" or just "*.png"
- "color" replaced by "albedo" to mach other places in the source tree
- fixed warnings
- clear the background when IBL is not used
Filament does not yet fully support threads with WASM, but this is a
baby step in that direction.
To enable experimental pthreads support, enable the WEBGL_PTHREADS CMake
option. This will enable pthreads support in `gltfio` and `utils`, which
is known to work, but not when served with GitHub Pages.
The web server must emit COOP, COEP and CORP headers, so our build
instructions now recommend the use of `emrun` for local testing.
This also changes our demos so that they do not use unpkg, which
does not work when using `emrun`, due to cross-origin restrictions.
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.
Just for fun, this is an example of a web component that allows you to
embed a Filament viewer with a single HTML element. It does not have
many features, but is much easier to use than our raw JavaScript API.
-DFILAMENT_SKIP_SAMPLES=ON with CMake
-Pfilament_skip_samples with gradle
This change also renames CMake options specific to Filament
to avoid clashes with subprojects.
With KTX, we should simply create the specified output folder and put
the KTX file(s) in there. There is no need to create a subfolder of the
output folder.
This change also allows users to pick a custom name for their KTX file,
because we only use the "deployment" name when generating filenames.
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.
We use R11F_G11F_B10F for HDR so we should stop checking for compressed
IBL files.
Also, make the glTF sample on web more consistent with the default
settings used by gltf_viewer on native and use venetian_crossroads
instead of syferfontein.
* Make CMake 3.10 the minimum version, add LTO option
* Install a newer CMake on Linux CI builds
* Update LLVM and Cmake on Windows CI
* Update build/windows/ci-common.bat

* Update formatting
* Apply suggestions from code review
* Update build/windows/ci-common.bat
* Update CMake
* Switch Android projects back to CMake 3.6
This is a more complex test than suzanne because it has multiple
materials and exercises the named materials functionality in
loadFilamesh.
This also exercises our glTF-to-Filamesh pipeline at build time.
See issue #663
* Turn on shaders optimization by default
Release builds of Filament only work well with optimize shaders,
turning optimizations on by default will help avoid mismatches.
This change also adds -g to disable all optimizations, for debug
builds.
* Use -g on debug builds
* Use -g on debug builds
* Update tutorial_redball.md to remove matc's -O
* Update tutorial_suzanne.md to remove matc's -O
* Use -g in debug builds
Note that the WebGL build uses filameshio, but Android does not. Our
Android samples therefore do not yet understand the compressed format.
For web, I measured the before / after:
```
BEFORE: filament.wasm = 505796, suzanne.filamesh = 521476
AFTER: filament.wasm = 510915, suzanne.filamesh = 333489
```
