1. A system for assuring the smooth motion of a graphical object presented on-screen at a display at a recipient node on a network in which data is transmitted from a source node on said network to said recipient node, comprising:
- means at said source node for transmitting data corresponding to the intended motion of said graphical object at said recipient node including an indication of the predictability of the motion of said graphical object; and
,means at said recipient node for receiving said data and said indication, and for smoothing said data in accordance with said indication.

Abstract
A system assures smooth motion in a distributed virtual reality environmenty categorizing the information to be transmitted as to the predictability of future motion and applying appropriate smoothing algorithms based upon knowledge of what the future motion is likely to be. The system switches between a linear interpolation algorithm for less predictable data and a Catmull-Rom spline for more predictable data.
