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 an d then project the normalized versions onto a unit cube (215). Each rotation a nd normal (200) is encoded according to on which face it was projected. In addition, motion can be compactly represented by movement across the unit cu be (215).
