A novel framework is proposed in this paper to simulate hybrid solids with deformable and rigid materials in real-time. Both types of materials are uniformly integrated into one spectral simulator. Based on the modal warping technique, we employ a new constraint strategy which eliminates the accumulation of approximation errors at the boundary interfaces, thus naturally gluing different materials. We also utilize the GPU to accelerate the run-time computation when updating the geometry of the hybrid solid—the most expensive step in this framework. This work provides a general-purpose solution of simulating hybrid objects in real-time, even for large-scale models. Copyright © 2010 John Wiley & Sons, Ltd. A real-time simulation solution for hybrid solid is presented. Deformable and rigid materials are glued together using a novel boundary constraint strategy while keep the system size small. The GPU aided implementation allows a real-time simulation even for large-scale models.
