Hi Li_Mingjie, thanks so much for your reply.
CesiumJsStreetViewCameraController seemed get height/latitude/longitude etc. info from 3dtiles data’s properties (case when point cloud data, properties set in batchtable and featruetable of .pnts) .
*Similar to this sandcastle sample.
One point cloud data file may has several billion points, i don’t know what problem will happen if set properties in batchtable and featruetable for all several billion points.
