Abstract

A method and system for encoding a video stream using a compact representation for rotations and normals. The method and system convert rotations and normals into normalized rotations and normals and then project the normalized versions onto a unit cube. Each rotation and normal is encoded according to on which face it was projected. In addition, motion can be compactly represented by movement across the unit cube.
