public delegate SurfaceChangedDelegate(surfaceId: VR.WSA.SurfaceId, changeType: VR.WSA.SurfaceChange, bounds: Bounds, updateTime: DateTime): void;
public delegate void SurfaceChangedDelegate(VR.WSA.SurfaceId surfaceId, VR.WSA.SurfaceChange changeType, Bounds bounds, DateTime updateTime);

Parameters

surfaceId The ID of the surface that has changed.
changeType The type of change this event represents (Added, Updated, Removed).
bounds The bounds of the surface as reported by the device.
updateTime The update time of the surface as reported by the device.

Description

The SurfaceChanged delegate handles SurfaceChanged events as generated by calling Update on a SurfaceObserver. Applications can use the bounds, changeType, and updateTime to selectively generate mesh data for the set of known surfaces.
