I was having a look at Greg's great demo of Bezier patches (http:// www.geepers.co.uk/software/bezier_patch_tutorial.html) and was wondering if anyone knows a simple way of generating draggable control nodes like he has implemented. So far the only way I see of doing it would be to generate a draggable box at each control point vertice, but was wondering if there was any built in feature to do this?
Thanks Robbie
