Paper Abstract

A new method for control of path motion is presented. To describe the motion of an object, we adopt two independent control curves, namely the path of the object in 3D space and the velocity curve of the object along the path in 2D space. Techniques for constructing the velocity curve according to various application are presented. The task of finding the exact position of the object along the path is facilitated by employment of a look-up table which matches the arclength of the path with a corresponding parameter value. An efficient arclength parametrization algorithm for path curve of Bezier form is developed.
