Abstract: Disclosed is a system and associated methods for compressing motion within an animated point cloud. The resulting compressed file encodes different transforms that recreate the motion of different sets of points across different point clouds or frames of the animation in place of the data for the different sets of points from the different point clouds. The compression involves detecting a motion that changes positioning of a set of points between a first point cloud and subsequent point clouds of an uncompressed encoding of two or more frames of an animation. The compression further involves defining a transform that models the motion, and generating a compressed animated point cloud by encoding the data of the first point cloud in the compressed animated point cloud, and by replacing the data for the set of points in the one or more subsequent point clouds with the transform.

Abstract: Disclosed is a system and associated methods for compressing data in a three-dimensional (“3D”) model. The system receives the constructs that form different shapes of a 3D object represented by the 3D model. The system selects a set of the constructs based on the set of constructs forming a particular shape that is compressible with a function. The system defines the function that generates an approximate shape for the particular shape formed by the set of constructs, and compresses the 3D model by replacing the set of constructs with the function. The system may tune the function so that the approximate shape matches the particular shape with more specificity, may define a noise pattern that approximates and applies the non-uniformity of the particular shape to the approximate shape, and may define a gradient pattern that approximates and applies the coloring of the set of constructs to the approximate shape.

Abstract: Disclosed is a security controller for a content distribution system that generates and encodes point clouds with invisible, visually undetectable, and/or tamperproof watermarks. The controller selects a set of data points from the point cloud, and changes at least one specific bit of a set of bits that define a value for a particular non-positional element of the set of data points. The controller encodes point cloud with a first watermark that is unique to a requesting client based on the changing of the at least one specific bit. The controller distributes the file encoded with the first watermark to the requesting client and tracks the set of data points that were encoded with the first watermark in order to subsequently verify that the requesting client was the original recipient of the point cloud encoded with the first watermark.
