Abstract
Extending earlier work on polynomial Bézier curves, we define
approximations to the length and energy of rational Bézier curves.
The approximations are defined directly in terms of the control
points and we investigates how the approximations behave under
subdivision. The approximation to the arc-length form the basis
for a fast recursive and adaptive algorithm which calculates the
arc-length of a rational Bézier curve.
