Abstract:
A system for generating a video bitstream representing a 3-D object, comprising:a database medium containing a dataset representing a layered decomposition from a triangle mesh of said 3-D object into multiple vertex layers and multiple triangle layers; means for determining from said dataset general strips of said triangles in which one vertex of each constituent triangle lies in a first vertex layer and the other two vertices of each constituent triangle lie in a vertex layer adjacent to said first vertex layer; means for determining from said dataset special triangles associated with any said triangle strip the vertices of which fall in the same vertex layer; means for encoding the triangles of each said general triangle strip, using values of two starting vertices of parent contour and child contour and of two common vertices of adjacent said triangles plus a bit march indicia; means for encoding said special triangles with a relative index defining the position of each said special triangle within said strip; and means for combining the encodings in an output to a transmission channel.
