Bezier

Description

The Bezier library (nicknamed PathMatics) provides powerful mathematical functionality for Bezier paths, from simple things like evaluating the length of a path to complicated things like inserting points on a path or constructing a smooth path from a list of on-curve points. Bezier math is not the easiest thing to grasp, but all the commands in this library are simple and straightforward, and they work magic on a textpath().

Note that the Bezier library is always in development, so you might experience occasional errors while working with it. Please report any errors (tomdesmedt@trapdoor.be).

A special thanks goes to professor F. De Smedt at the Free University of Brussels for his integration and interpolation algorithms.

Commands in the Bezier library

• contours()
• length()
• point()
• split()
• findpath()

Example

A basic example of path math: the point() command tells us where to put circles on the textpath, playing around with curves and their control handles constructs the whirly background.
