The spheres are placed a bit over the table surface so that their geometries' surfaces
aren't accidentally crossing each other, an effect known as
interpenetrating
. When sur-
faces interpenetrate, the dynamics that result are usually as welcome as sand in your eyes.
Starting all colliding rigid bodies slightly away from each other should guarantee that
their surfaces don't interpenetrate. Using the simple pool table that you've set up will
make the dynamics calculations quick and easy.
