Abstract: Generally, a scanning device performs a sonic scan of a space by generating an ultrasonic impulse and measuring reflected signals as raw audio data. Sonic scan data including raw audio data and an associated scan location is forwarded to a sonic mapping service, which generates and distributes a 3D map of the space called a sonic map. When multiple devices contribute, the map is a collaborative sonic map. The sonic mapping service is advantageously available as distributed computing service, and can detect acoustic characteristics of the space and/or attribute visual/audio features to elements of a 3D model based on a corresponding detected acoustic characteristic. Various implementations that utilize a sonic map, detected acoustic characteristics, an impacted visual map, and/or an impacted 3D object include mixed reality communications, automatic calibration, relocalization, visualizing materials, rendering 3D geometry, and the like.
