Bouncer

A Bouncer is an object that is very similar to a Floor. A particle hitting a bouncer will bounce off like a tennis ball. However, unlike a Floor, a bouncer is a line segment that is added by a press/drag/release sequence as in the Segment mode. Bouncers are very powerful objects for creating environmental limits to a simulation scenario. The following picture demonstrates a bouncing ball inside a polygonal region. Each edge of the region is an individual bouncer.
