| 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.
