Setup Magic Leap 2 and Test Extension

[corybarr]

We have a Magic Leap 2 in house. Set it up and test out the extension. Evaluate how demo-able it is.

Instructions for Running

Software Installation:

The CESIUM DEMO LAPTOP 2 already has all software installed. If you want to set up a different computer, see the developer docs for Magic Leap.

Turning on the Demo:

Assuming the above steps are complete, to run the demo follow these steps:

1. Turn on the Magic Leap. Make sure you can see the launch bar.
2. Use a WiFi connection. Do not tether the control pack to the computer via USB cable.
3. Keep the Magic Leap on for the following steps. Setting it down will turn it off, and it might not link.
4. Open NVIDIA Omniverse Composer.
5. In Composer, load or create the scene you wish to view.
6. Open the AR widget window. If you don’t see it, you can foreground it by selecting this menu option:
7. Window->Rendering->AR
8. Press Start AR in the AR widget.
9. Open the Magic Leap Hub

Notes:

• At present, moving your head will not update which tiles are visible. The OpenXR extension uses a different camera frustum for the headset than what the Cesium for Omniverse extension is using to query for tile visibility.
• You cannot move around in the demo. OpenXR allows the point-and-click style of moving. However, this doesn't currently work the the Fabric Scene Delegate enabled. This is most likely due to the navigation method needing to raycast, and physics currently do not work in Fabric. You can move around in USD scenes that do no have Fabric enabled.
