To learn more about subdivision and wavelets check out these Java
applets which were written by members of the group, collaborators, and
friends.
- Chaikin's Algorithm: This is
probably one of the simplest subdivision schemes around. It is also
known as coner cutting and corresponds to a neat way of generating
quadratic B-splines.
- 4 Point Algorithm: This is a simple
interpolatory subdivision scheme.
- Irregular
4 Point Scheme: Igor Guskov wrote this little applet demonstrating
that the 4 point scheme remains smooth even in a fully irregular setting.
- Cascade:
Wim Sweldens wrote this neat applet illustrating subdivision for the
entire family of 4-tap filter wavelets.
- Lifting:
Michael Astle built an applet together with Dae Kang demonstrating
some of the ideas underlying the lifting scheme.
- Multiresolution,
Control-Point-Free Editing: As part of his CS274b project (1996)
Dmitri Linde did this wonderful applet demonstrating some
multresolution editing ideas in 1D.
- Bezier Curves and
B-splines: Another beautiful applet by Dmitri Linde shows how
Bezier curves and B-plines of any order can be generated through
subdivision, i.e., repeated knot insertion.
