The problem is that when computer scientists get advancedthey start using maths, the traitorous bastards. The ones who are still capable of explaining stuff in English don't know the answers.

I think that means De Boor is just for drawing a curve with a lot of control points. Didn't occur to me that was much of a problem, but apparently so.
I have a question going on here: en.wikipedia.org/wiki/Wikipedia:Reference_desk/Mathematics#Bezier_curve_with_width

they fucking well do as well, and that.I've been struggling for months with mathematical 'pseudocode' algorithms that have just a bit too much "assume an infinite set of things" to be feasibly implemented as code :(((
are these algorithms mean to take a curve, and produce the control points, or take some points, and produce the control points of the curve that fits them?

I need the second of those things.The algorithms, I think, judging by the pictures, are just for quickly drawing a point on a curve defined with lots of control points (what k3b/-\b would call an "degree lots polynominal" I think). Therefore useless to me. Really I just want to know how to find the edge-path for a curve with a width, so I can fill inside and thereby draw a nice fat curved line with an even width, for the flash renderer I'm writing.
