Put together a nice demo

[cdata]

@ffu : @smalls mentioned you might have time to do a variation of shop w/ 3D content

[smalls]

And @yuinchien

The demo will look very similar to this: https://shop.polymer-project.org/

We need assets and data for the xr-model demo. We should have 2 to 3 categories and for each category it should have 6 product items preferably. And for each item we need to have

• 3D model in gltf format (and usdz if ARKit is supported) and it should just work in <xr-model> without manual configs like setting x/y/z coords to align correctly.
• image (png, jpg,...) for the item
• name, price and description (See this example)

Assign to @smalls for providing the above.

Our demos have been getting better and better, and I think they're now in good shape. In particular our annotations and WebXR demo pages show off model viewer quite well.
