    abstract     = "A system for interactive modelling of {3D} shapes on a
computer is presented. The system is intuitive and has a flat learning curve. It is especially well suited to the creation of organic shapes and shapes of complex topology. The interaction is simple; the user can either add new shape features or smooth and deform existing features."
