Speech synchronization for physics-based facial animation

Abstract

This article presents a method for unraveling the hypercube and obtaining the 3D-cross (tesseract) that corresponds to the hyper-flattening of its boundary. The hypercube can be raveled back using the method in an inverse way. Also a method for visualizing the processes is presented. The transformations to apply include rotations around a plane (characteristic of the 4D space). All these processes can be viewed using a computer animation system.
