TinyUSDZ JS/WASM
Demo app
See demo folder.
It uses npm package of tinyusdz, so no WASM building required.
Technical note on JS/WASM version of TinyUSDZ
Please see wiki https://github.com/lighttransport/tinyusdz/wiki/WASM-and-JavaScript-module
For library developers
See js folder for JS codes.
Building WASM module
Emscripten and emcmake required.
See /.github/workflows/wasmPublish.yml or
$ ./bootstrap-linux.sh
$ cd build
$ make
wasm module(tinyusdz.js and tinyusdz.wasm) will be output to js/src/tinyusdz folder.
Note
- asyncify is disabled since it increases code size ~2.5x
Code size
tinyusdz.wasm
2025/05. emsdk 4.0.8. -Oz : 1.6 MB 2025/06. emsdk 4.0.9. -Oz : 1.9 MB
zstd compression
we recommend to use zstd compression for wasm binary in the deployment.
for example, 1.9MB tinyusdz wasm can be compressed to 400KB with -19 compression level.
Prepare wasm.zstd
$ zstd -19 tinyusdz.wasm
See js/src/tinyusdz/TinyUSDZLoader.js to how to load zstd compressed wasm.
stack size
