usd-viewer

usd-viewer demo

Experimental Web Component for rendering USDZ 3d format. Built on the experimental work and efforts of github.com/autodesk-forks/USD/tree/release

Instalation

npm install usd-viewer

Web Assembly Dependencies

Currently this depends on the SharedArrayBuffer so to enable in the browser the following response headers must be set:

"Cross-Origin-Embedder-Policy": "require-corp"
"Cross-Origin-Opener-Policy": "same-origin"

To load the Wasm dependencies in the browser copy them from the node_modules into your host env.

cpy node_modules/usd-viewer/wasm/**/* dist/wasm

To change the default path (./wasm) of the Wasm resources add the following meta tag to the document.

<meta name="usd-viewer:wasm" content="custom-path/wasm" />

Usage

<script type="module">
  import 'usd-viewer/include.js';
</script>

<usd-viewer src="./usd/perseverance.usdz" alt="Perseverance Mars Rover"></usd-viewer>
