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.

The 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 was developed as a research project by Takeo Igarashi and is implemented as a Java program.

Watch the above video demostrating the use of the applet, and then try it yourself at the creator’s site! A free download is also available there, although I would suggest to visit the SmoothTeddy the new enhanced version of the program to experiment.
