Foil 98 PositionInterpolator - II

From VRML 2 Basic Concepts and Definitions CPS616 -- Information Track of CPS -- Spring Semester 98. by Zeynep Ozdemir, Rob Baker, Meryem Ispirli, Geoffrey C. Fox
1 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.
2 Whenever interpolator receives a set_fraction event, it computes a new position value (according to keyValues) and places it in a value_changed eventOut.
3 By wiring this eventOut which holds a 3-vector to the Transform node's appropriate eventIn attribute, the animation can be implemented.
