A couple other examples are Jon Cohen's Simplifaction Envelopes at:

http://www.cs.unc.edu/~geom/envelope.html

and Michael Garland's Qslim.

http://graphics.cs.uiuc.edu/~garland/software/qslim.html

Garlands code is the fastest I've seen.

Also Will Schroeder's algorithm is implemented in the VTK source code.
