reparameterizing part of a curve?
Friday, 30 August 2002 Fri, 30 Aug '02
Can anyone explain how to reparameterize a portion of a curve? Consider a situation where one is happy with the region u=0.0-0.5 and u=0.75-1.0 but wants to tweak the intervening section without affecting (in the 'u' sense) the outer bits. In my specific case, the curve is polygonal where u is distributed equally over the number of vertices. I would like to choose a number of consecutive vertices along a section of the curve, tweak their positions, resample this section even, all without affecting the u of nonselected vertices. I'll spare you my failed attempts at realizing the above. The more I think about it, the less I'm sure that it's even conceptually possible. Cheers, Darran. P.S. Can you cc this to me directly as I'm on the digest version of the list and won't see any responses until midnight, my time.
