Interactively Cutting and Constraining Vertices in Meshes Using Augmented Matrices

Yu-Hong Yeung, Jessica Crouch, Alex Pothen We present a finite element solution method that is well-suited for interactive simulations of cutting meshes in the regime of linear elastic models. Our approach features fast updates to the solution of the stiffness system of equations to account for real-time changes in mesh connectivity and boundary conditions. Updates are […]

Simit: A Language for Physical Simulation

Fredrik Kjolstad, Shoaib Kamil Jonathan Ragan-Kelley, David I.W. Levin,Shinjiro Sueda, Desai Chen, Etienne Vouga, Danny M. Kaufman, Gurtej Kanwar,Wojciech Matusik, and Saman Amarasinghe Using existing programming tools, writing high-performance simulation code is labor intensive and requires sacrificing readability and portability. The alternative is to prototype simulations in a high-level language like Matlab, thereby sacrificing performance. […]
