Techniques to Rapidly Create Simple 3D Objects
Free–form strokes are also being used for rapidly designing
3D free–form objects.
(Igarashi, Matsuoka, & Tanaka 1999) present a gesture–
based sketching interface (TEDDY) to quickly and easily
design 3D free–form models out of 2D sketched strokes. In
their system the designer first interactively draws 2D free–
form strokes depicting a 2D silhouette. A 3D polygonal object
is automatically constructed by inflating the region surrounding
the silhouette, making wide areas fat and narrow
ones thin.
