what's new for Spatial Personas in visions 2?

In VisionOS 2, there are several new features for enhancing spatial experiences, particularly for Spatial Personas. These include:

1. Scene Understanding Enhancements: The fidelity of scene understanding capabilities has been significantly extended. Planes can now be detected in all orientations, allowing for anchoring objects on various surfaces in your surroundings. Additionally, room anchors have been introduced, which consider the user's surroundings on a per-room basis, and you can detect a user's movement across rooms.

2. Object Tracking API: A new object tracking API for VisionOS allows you to attach content to individual objects found around the user. This functionality enables attaching virtual content, like instructions, to physical objects, providing new dimensions of interactivity.

3. Volume Resizing: VisionOS 2 makes it easy to resize volumes, similar to resizing a window. Users can now resize volumes themselves, enhancing the flexibility and interactivity of spatial apps.

These updates are part of the broader enhancements in VisionOS 2 aimed at creating richer spatial experiences that leverage depth and space more effectively.
