- Add methods for adding attributes to the input mesh
- Add method in TangentSpaceMesh for when user provides the
tangents
- Separate client-side Algorithm enum from implementation algorithm
(AlgorithmImpl)
- Fix CMake config for combining static libs
* Add Transcoder API for C++ clients.
We will add JavaScript and Java support in a later PR.
* Transcoder: use fixed inner loop in some cases.
This lets clang produce better ARM code for common cases.
* Transcoder: stronger typing in Config, etc.
* Transcoder: add UTILS_RESTRICT and noexcept.
Note that libgeometry is already included in `filament-android`, this
simply exposes more of its existing functionality.
The Java version of SurfaceOrientation is similar to the JavaScript
version because we are bundling it into the main Filament package, even
though it is a separate library in C++. This is much simpler than
creating a brand new Java package.
New Android sample that tests this is forthcoming.
Fixes#1729.
This "fixes" the new animated Fox model in the glTF conformance suite.
As per the glTF spec, we now generate per-face normals for the case
where normals are not specified in the model.
Note that true flat shading (i.e. flat interpolation) is not a
requirement in the glTF spec, since some Khronos members advocate for
WebGL 1.0 compatibility.
Fixes#2088.
This moves our existing VertexBuffer utility into a new "geometry"
library and adds new functionality for computing tangents based on UV's.
The UV-based method comes from Eric Lengyel.
We considered mikktspace (which thankfully has a zlib-style license) but
it would require re-indexing via meshoptimizer and is therefore a bit
heavyweight.
The new library has no dependencies and will add only 7 KB to Filament's
Android aar file.
Fixes#858 and preps for #528.
