Line Drawings of 3D Shapes

Welcome

This site describes recent research on line drawings of 3D shapes, including studies on how artists create drawings and how people interpret drawings.

So far, this work involves two studies. The first, "Where Do People Draw Lines?," investigates how artists' drawings of 3D shapes correlate with the mathematical properties of the shapes, and known computer graphics line drawing techniques. The second, "How Well Do Line Drawings Depict Shape?," examines how people interpret line drawings, both hand-drawn and computer-generated, and when depiction succeeds and fails.

The results of these studies are available in full from this site.
