METHOD AND SYSTEM FOR ENCODING ROTATIONS AND NORMALS IN 3D GENERATED SCENES

摘要

A method and system (102) for encoding a video stream using a compact representation for rotations and normals (200). The method and system (102) convert rotations and normals (200) into normalized rotations and normals and then project the normalized versions onto a unit cube (215). Each rotation and normal (200) is encoded according to on which face it was projected. In addition, motion can be compactly represented by movement across the unit cube (215).
