Area Targets in Vuforia do a great job of matching a LiDAR scan to the room it was scanned in.
Would I be able to use the point cloud scans from the iPad to do the same in RealityKit on a 1 to 1 scale as does Vuforia?
"Underscore 1 to 1".
Vuforia Area Target supports scans made with RealityKit-enabled devices with LiDAR Scanner.
So an answer is obvious: Yes, you can.
