Abstract
Systems and methods relate to encoded video streams including geometric-data streams transmitted to a receiver for rendering of a viewpoint-adaptive 3D persona. A method includes obtaining at least one triangle-based three-dimensional (3D) submesh of a subject, wherein the obtained triangle-based 3D submesh includes a plurality of submesh vertices that define a plurality of submesh triangles, identifying a plurality of strips of the submesh triangles, generating triangle-strip data representing the identified strips of submesh triangles, generating compressed-submesh data that includes the triangle-strip data, and transmitting the compressed-submesh data to a receiver for reconstruction of the triangle-based 3D submesh of the subject.
