Accuracy Metrics and Benchmarks for Simulations of Deformable Objects
نویسنده
چکیده
− There are a number of algorithms for interactively modeling deformable objects, such as soft human tissues. Because of the desire for real-time performance, approximations are made to quickly calculate deformations. This paper proposes accuracy metrics and benchmarks to allow a systematic comparison of simulation algorithms for deformable objects in 2D and 3D. We implement and compare the computed deformations of several algorithms based on the finite element method (FEM) that rely on the approximations of explicit time integration, mass lumping, or quasi-static motion. We also compare different material properties and show that some algorithms limit the breadth of materials that can be simulated.
