Generation and Fracturing of Thick Shells

In this paper we present methods to generate and animate shells with a pre-defined thickness. Given a polygonal surface mesh, a thick shell is constructed by computing a second, extruded polygonal surface. We introduce methods to simulate deformation and fracture of thick shells in realtime. Mass-spring models are used in this context. A novel simulation framework to generate, animate and interact with shells in real-time has been created. The entire pipeline of shell animation may be handled, starting at the generation of shell, continuing on to deformation and fracture and ending with rigid body simulation of fractured shell fragments.
