Teddy is a sketch-based modeling system to quickly and easily design
freeform models such as stuffed animals and other rotund objects. The user
draws several 2D freeform strokes interactively on the screen and the system
automatically constructs plausible 3D polygonal surfaces. Our system
supports several modeling operations, including the operation to construct a
3D polygonal surface from a 2D silhouette drawn by the user: it inflates the
region surrounded by the silhouette making wide area fat, and narrow area
thin. Teddy, our prototype system, is implemented as a Java program, and
the mesh construction is done in real-time on a standard PC. Our informal
user study showed that a first-time user masters the operations within 10
minutes, and can construct interesting 3D models within minutes.
