Abstract
Video of a scene is generated and presented to a user. A stream of mesh models of the scene and a corresponding stream of mesh texture maps are generated from one or more streams of sensor data that represent the scene. Each of the mesh models includes a collection of faces, and each of the mesh texture maps defines texture data for one or more points on the faces. Each of the mesh models is broken down into convex sections. Each of the convex sections is surrounded with a three-dimensional hull. The texture data that is associated with each of the faces in the convex section is projected onto the three-dimensional hull, and a hull texture map for the convex section is produced.
