Abstract: A three-dimensional (3D) graphics system automatically corrects the orientation of different 3D models based on a classification of the objects represented by each 3D model. The 3D graphics system receives a 3D model that is defined with multiple primitives distributed in a 3D space. The 3D graphics system determines a classification based on the primitives having a unique pattern, commonality, or feature that differentiates a particular object from other objects. The 3D graphics system maps points-of-reference that are associated with the classification to two or more primitives in the 3D space of the 3D model, generates an orientation vector based on the points-of-reference, and adjusts an orientation with which the 3D model is presented based on the orientation vector.

The system detects an interaction with primitives of a particular classification, and animates the primitives according to an animation model that is defined for an object identified with the particular classification.

Abstract: A multi-dimensional encoder (“MDE”) receives a file with different data points. Each data point is defined with uncompressed multi-dimensional data. The multi-dimensional data may include multiple elements for defining a data point position (e.g., a multi-dimensional position including x, y, and/or z coordinates), color values of the data point (e.g., red, green, and blue), and/or other data point attributes. The MDE assigns an index to each data point or each data point element, and maps the data points to a frequency domain based on a frequency with which values occur in two or more of the elements (e.g., multiple dimensions). The MDE generates a line that represents the frequency, and provides a compressed file format to a requesting device that includes the line and different sets of indices that are associated with different frequencies represented by the line.
