Ok, without looking it up, who knows what NURBS stands for?

Non-Uniform R? Bezier Splines

^ rational

Umm... not quite. Any other takers?

That's close though. The reason I ask is because I have tried to commit it to memory several times and I always forget it's such a strange combo of words

hrmph.... now i'm gunna have to go cheat.

Non-Uniform Rational B Spline
As I recall, B does not stand for Bezier curves. But instead, means a spline defined by control points.

Edit: And rational stands for rational numbers that are used to describe the location of these points.

B not = Bezier?
Someone lied to me!

Thanks for explaining Rational. At first I thought they tossed it in there so they wouldn't be called NUBS.

Never Underestimate Really Big Sticks :P

Yea for Dan! Yep, that's it and I can *never* seem to remember it without looking it up. You can really impress your friends if you use that in a conversation, ha!!! ...and you can really feel like a dork when you get it wrong and someone looks it up and calls you on it

Uh... a Bezier spline *is* a spline defined by control points. As are every other type of spline. A Bezier spline is the kind used in Illustrator. Are you sure the B doesn't stand for Bezier?

Also, I wouldn't be surprised if the S stands for "surface."

except Slime that it's

Non
Uniform
Rational
B-
Spline

Nurbs objects can be made by non-bezier splines too.

Heres a java applet that shows the difference between Bezier and B-Spline. Notice that the control points better define where the line goes
