unevenly divided surface

by Tim

Sep 7, 2009

hi,
sorry i have to bug all again.

i can't figure out why with these GH settings (please check image) the loft surface generated in Rhino is splitted/divided unevenly in the V(X) -direction.

is it me, is it Rhino, GH or "only" my computer that is sooo wrong?

i'm just soo tired encountering these kinds of errors all the time.


thanks

    Hi Timo,

    Well, it all depends on what you mean by "unevenly" ...

    As David Rutten exaplains (here, p.78):

    "the progression of the domain of a surface is not linear (it might be compressed in some places and stretched in others, especially near the edges where the surface has to be clamped), the distance between isocurves is not guaranteed to be identical either."

    In chapter 7 of the Primer you'll find extensive information about Nurbs curves and surfaces - be sure to take a look at it.

    When you do, you will understand perfectly what is going on here:


    Good luck!

      I read your post again and I'm pretty sure this is in fact what you wanted.

      It seems I've made a fool out of myself with all the off-subject smart talking :)

      What you need to do is rebuild that surface directly in Rhino.
      (select the surface, enter "Rebuild")

      Sorry for all the commotion.
