It involves both modeling the internal material properties of the textile and the interaction with the surrounding scene. We present a parallel cloth simulation approach designed for distributed memory parallel architectures, in particular clusters built of commodity components. In this paper, we focus on the parallelization of the collision handling phase. In order to cope with the high irregularity of this problem we employ a task parallel approach with fully dynamic problem decomposition. This leads to a robust algorithm, regardless of the complexity of the scene. We report on initial performance measurements indicating the usefulness of our approach.Categories and Subject Descriptors (according to ACM CCS): C.1.4 [Processor Architectures]: Parallel Architectures, G.1.3 [Numerical Analysis]: Numerical Linear Algebra, G.4.5 [Mathematical Software]: Parallel and Vector Implementations, I.3.7 [Computer Graphics]: Three- Dimensional Graphics and Realism
