Here is a small collection ofsubdivision and wavelet related applets that students, collaborators,and I myself have written. Check them out!<ul> <li>A simple demonstration of how to draw smooth curves through <!WA2><a href="http://www.cs.caltech.edu/~ps/java/chaikin.html">corner cutting</a> (and my first attempt at Java...). This is an instance of subdivision which is intricately linked to wavelet constructions. <li>One of the students in CS274b, Dmitri Linde, took this applet as a starting point for his <!WA3><a href="http://dmitri.caltech.edu/cs284/h2">homework</a> assignment. It demonstrates B-splines and Bezier curves of varying order and lenght all rolled into one application. They are all generated through subdivision. <li>Dmitri Linde also implemented his <!WA4><a href="http://dmitri.caltech.edu/cs284/proj">CS274b project</a> in Java.
