Abstract
A processor implemented method for compressing time-varying surface data of a 3 dimensional object in a global digital space having frames, using a video encoder that supports a video data compression algorithm, the video encoder being coupled to a transmitter. The method includes the steps of (i) decomposing the time-varying surface data into at least one surface representation that is encoded in an oriented bounding box, (ii) transforming the oriented bounding box into a canonical camera representation for each frame to obtain canonical coordinates for the at least one surface representation, (iii) converting each of the at least one surface representation into at least one bounding box video pair that includes a grayscale video representing depth, and a color video and (iv) tiling the at least one bounding box video pair for each frame to produce a tiled bounding box video.
