Abstract

We present three new building primitives for surface modeling systems using splines. The first two, welding and pinching, are used to interactively create more complex objects by combining and by distorting spline surfaces. The welding automatically adjusts the edges to be welded, while the pinching creates continuous junctions of tubular surfaces. The last modeling primitive builds on the first two to "flesh" the skeleton of an object with a regular "skin".
