How would you call this feature in a NURBS modeler?

Hi Colin,

thanks for the links, very interesting too. The modeling techniques shown in all videos seems to be a strenght of those programs, besides bitmap (depth map images) import for relief generation. The additional sculptings tools etc. in JDPaint for example are a big plus too.
