ouncing beachball (with prototype and JavaScript): this world illustrates the use of a PROTO to encapsulate a Script node, timer, shape, and routes to create a vertically bouncing beach ball. The bounce path is based upon the projectile motion equation of physics, constrained to create a cyclic bouncing path with a user-selected maximum bounce height. Also, there is no friction, drag, or damping. For an explanation of the script, see bounce1.wrl.
