Processing and/or transmitting 3D data
Systems and techniques for processing and/or transmitting three-dimensional (3D) data are presented. A partitioning component receives captured 3D data associated with a 3D model of an interior environment and partitions the captured 3D data into at least one data chunk associated with at least a first level of detail and a second level of detail. A data component stores 3D data including at least the first level of detail and the second level of detail for the at least one data chunk. An output component transmits a portion of data from the at least one data chunk that is associated with the first level of detail or the second level of detail to a remote client device based on information associated with the first level of detail and the second level of detail.

a processor configured to execute the following computer executable components stored in the memory:
a partitioning component that receives captured three-dimensional (3D) data associated with a 3D model of an interior environment and partitions the captured 3D data into at least one data chunk; and
an output component that transmits, to a remote client device, first visual texture information for the at least one data chunk at a first resolution and subsequently transmits, to the remote client device, second visual texture information for the at least one data chunk at a second resolution that is greater than the first resolution in response to a determination that a viewpoint associated with a rendering of the 3D model on the remote client device satisfies a defined criterion.
