12 spline TECHNIQUES

Grab the original ribbon surface and go into Isoparm mode. select an isoparm at the 0.5 mark in V (for example, select r ribbonplane_srf.v[0.5]). Use the Edit Curves>duplicate surface Curves menu item to duplicate that isoparm. This will give you a curve that follows the ribbon, by keeping its history. you can then use that curve to plug into a curveinfo node and set up your typical squash and stretch node networks. There is no limit to how many layers you create, so make sure that you experiment with these techniques and try to explore more on your own! Plug the curve shape into the curveinfo node to obtain the arclength. Use this to drive how much stretching happens on the joints attached to the surface. Here’s a final look at the ribbon used on the snail’s eye stalks – three layers, with the final layer being the actual individual control over the skinned joints. This was necessary to achieve some of the waving effects.
