Real-time geometric motion blur for a deforming polygonal mesh

Motion blur is an important method for increasing the visual quality of real-time applications. This is especially true in the area of interactive applications, where designers often seek to add graphical flair to their programs. In many cases, these applications use animated characters, where a polygonal mesh is wrapped around an animated skeleton. As the skeleton moves, the mesh deforms. In this paper, we present a method for adding a geometric motion blur to a deforming polygonal mesh. The scheme we present keeps track of a character's motion silhouette, and uses this to create a polygonal mesh. When this mesh is inserted into the scene, it gives the appearance of an artistic motion blur for an object or particular character. This method is generic enough to work on nearly any type of moving polygonal model, and also approximates swept volumes.
