    Abstract:

    By using some new ideas of form conversion and expression simplification for rational Bézier curves, also by using Cauchy's inequality, some new close estimates for the heights of degree n (n=2,3,4) rational Bézier curves which are in common use in geometric shape design are investigated. Thus the former termination criterions for subdivision of rational Bézier curves are improved. This work is very valuable for reducing computing time and increasing efficiency.
