# tinyusdz
"tinyusdz" C++ project provides USD/USDA/UDSC/UDSZ 3D model file format suport
## Automatic repo clone
tinyusdz repo is automatically cloned. Users who haven't opted-in to USD support
won't be burdened with the extra download volume.
To update the git commit hash pulled down, modify `TINYUSDZ_GIT_TAG` in file
`code/CMakeLists.txt`
## Notes
Couldn't leverage tinyusdz CMakeLists.txt. Fell back to compiling source files specified in
"android" example.

# Tinyusdz patch files
Pending acceptance of proposed changes upstream, need to resort to patching to keep things moving
## Tinyusdz files needing patches
### `tinyusdz_repo/src/external/stb_image_resize2.h`
Without patch, build will fail for armeabi-v7a ABI via android NDK
Add `#elif` block as indicated below around line `2407`
```
#elif defined(STBIR_WASM) || (defined(STBIR_NEON) && defined(_MSC_VER) && defined(_M_ARM)) // WASM or 32-bit ARM on MSVC/clang
...
#elif defined(STBIR_NEON) && (defined(__ANDROID__) && defined(__arm__)) // 32-bit ARM on android NDK
static stbir__inline void stbir__half_to_float_SIMD(float * output, stbir__FP16 const * input)
{
// TODO: this stub is just to allow build on armeabi-v7a via android NDK
}
static stbir__inline void stbir__float_to_half_SIMD(stbir__FP16 * output, float const * input)
{
// TODO: this stub is just to allow build on armeabi-v7a via android NDK
}
static stbir__inline float stbir__half_to_float( stbir__FP16 h )
{
// TODO: this stub is just to allow build on armeabi-v7a via android NDK
return 0;
}
static stbir__inline stbir__FP16 stbir__float_to_half( float f )
{
// TODO: this stub is just to allow build on armeabi-v7a via android NDK
return 0;
}
#elif defined(STBIR_NEON) && defined(_MSC_VER) && defined(_M_ARM64) && !defined(__clang__) // 64-bit ARM on MSVC (not clang)
```
