The ToonFace system is primarily a research tool. As such, it is still missing a number of features that
would be desirable and not too difficult to implement. For the Editor, a useful feature would for example be
multiple-level UNDOs, as well as improved user interface layout. Also, adding animation libraries to the Editor
would help a designer envision what a face looks like when it moves. Currently the animator has no user interface
for adjusting such things as background color, size of the face, or window. These would all make the system easier
to use. Looking further along, control points allowing the nose and ears to move would extend the kinds of
creatures that can be designed in the system. A feature that allowed a face to be texture-mapped onto threedimensional
shapes would of course improve the look of the system quite a bit. The control point scheme described
here is easily applicable to more conventional three-dimensional computer graphics, keeping the simplicity without
compromizing facial expression.
