Foil 94 PositionInterpolator - II

From VRML 2 Basic Concepts and Definitions CPS616 -- Information Track of CPS -- Spring Semester 97. by Zeynep Ozdemir(Geoffrey C. Fox)
A simple animation can be implemented by the following routings. The fraction_changed eventOut of a TimeSensor node can be wired to a set_fraction eventIn of interpolator.
Whenever interpolator receives a set_fraction event, it computes a new position value (according to keyValues) and places it in a value_changed eventOut.
By wiring this eventOut which holds a 3-vector to the Transform node's appropriate eventIn attribute, the animation can be implemented.
