Abstract
A sketching system for spline-based free-form surfaces on the Responsive
Workbench is presented. We propose 3D tools for curve drawing and deformation
techniques for curves and surfaces, adapted to the needs of designers. The user
directly draws curves in the virtual environment, using a tracked stylus as an
input device. A curve network can be formed, describing the skeleton of a
virtual model. The non-dominant hand positions and orients the model while the
dominant hand uses the editing tools. The curves and the resulting skinning
surfaces can interactively be deformed.
