Pointers to Papers and Home Pages

In no particular order the following list points to relevant resources regarding splines and subdivision surfaces

Joe Warren's home page, which has links to his papers;
The Grail home page at UW has tons of pointers. So does the home page of Tony DeRose;
Lots of spline papers live on the home page of the Graphics Group at the University of Erlangen, including some good introductory materials;
Amos Ron's home page has some pointers to scaling function papers;
Carl de Boor's page has more spline stuff than you can shake a stick at;
Jörg Peters' home page has pointers to online versions of all his papers;
Hugues Hoppe has done some great work with surfaces;
Marian Neamtu has done a lot of work with splines and approximation theory;
Larry Schumaker also has lots of spline and approximation theory contributions;
David Donoho has done some very deep work on understanding refinable functions and the smoothness spaces they span.

There are also many papers which I have snarfed and which you can get locally by rummaging through a directory (if you go into these directories, be sure to push the reload button or you won't get complete listings [some kind of netscape bug I presume]).

A cool gallery of Catmull-Clark subdivision surfaces was put together by Mark Duchaineau.
