Very interesting. When I first read the subject, I assumed that it was some
buzzword for an already existing technology. I looked up some of the papers,
and I was wrong! It's a generalization of bspline surfaces in that they allow
t-junctions in their control cage instead of having unecessarily extend the
cage where it's not needed. The tech also extends to subdivision surface cages,
requiring way fewer subdivisions, while acheiving the same accuracy. 



Manson: My philosophy is:  Don't think.  I don't believe in the mind that you think with and scheme with.  I don't believe in words.

Reporter: If you don't believe in words, why do you use so many of them?

Manson: Words are symbols.  All I'm doing is jumbling the symbols in your brain.  Everything is symbolic.  Symbols are just connections in your brain.  Even your body is a symbol.
