# Driving the Bend Deformer Question

 10 October 2012 ogbonna Veteran portfolio Nathaniel Anozie Baltimore, USA Hi, Here is an idea that may be helpful. There probably is a much simpler solution, and I may have made some mistakes in this explanation. It involves gluing nodes onto a surface. It involves binding joints to a curve. What if the length of a curve that moves with the Nurbs sphere's cvs drives the bend deformer's curvature. How can a curve be bound to the Nurbs sphere? 1. glue joints onto the sphere see picture I made (here I showed 3 joints) http://flic.kr/p/dmKpXY. 2. smooth bind the curve to the joints. 3. use a curveInfo node to get the length of the bound curve 4. after some kind of scaling connect the scaled arcLength to the bend deformer's curvature Now transformations of the sphere would change the curve length which could then be scaled and drive the bend deformer curvature. And maybe the world rotations of one of the bound joints can drive the bend deformers rotation. For information on gluing nodes onto a surface check out Matt Estela's wonderful explanations under Rigging and Surface, CV, and Curve constraints.

 10 October 2012 albros435 New Member portfolio Steph Rome, Italy Hi Nate, thanks for your help ! Actually I found a simpler solution, I know it's not the correct one, but at least its working fine. _ I created 2 Bend Deformers for the head. _ Then I connected the nurbsSphere tX to the 'curvature' of the 1st 'Bend_Handle'. _ Later I rotated on Y the 2nd 'Bend Handle' and connected it to the nurbsSphere tZ . . and it's deforming pretty fine ! share quote
