The pe Rigid Body Physics Engine

This research project focuses on the development of the pe physics engine. pe is an advanced C++ framework for the simulation of rigid, completely undeformable bodies with arbitrary shape. pe offers both collision solvers for physically accurate simulations as well as fast solvers suitable for computer games. The major focus of pe are large-scale and massively parallel rigid body simulations with up to several billion interacting rigid bodies. The currently largest simulation with 28 billion non-spherical bodies was performed on the SuperMUC Petascale System at the Leibniz Supercomputing Center on 262144 processor cores.
