Declaration
public abstract TrackableChanges<XRTrackedImage> GetChanges(XRTrackedImage defaultTrackedImage, Allocator allocator)Parameters
| Type | Name | Description |
|---|---|---|
| XRTrackedImage | defaultTrackedImage | An XRTrackedImage populated with default values. The implementation should first fill arrays of added, updated, and removed with copies of this before copying in its own values. This guards against additional fields added to the XRTrackedImage in the future. |
| Allocator | allocator | The allocator to use for the returned data. |
Returns

| TrackableChanges<XRTrackedImage> | The set of changes to tracked images (added, updated, and removed) since the last call to this method. |
