  abstract = {This paper presents a modeling system which takes advantage of
              two-dimensional drawing knowledge to design three-dimensional
              free-form shapes. A set of mouse or tablet strokes is interpreted
              by the system as defining both a two-dimensional shape boundary
              and a displacement map. This information is used for pushing or
              pulling vertices of existing surfaces, or for creating vertices of
              new surface patches. To relieve the burden of 3D manipulation from
              the user, patches are automatically positioned in space. The
              iterative design process alternates a modeling by drawing sequence
              and a viewpoint change. To stay as close as possible to the
              traditional drawing experience, the system imposes the minimum
              number of constraints on the topology of either the strokes set or
              the resulting surface.},
