This site contains data related to the Princeton Graphics Group's study of human artists' drawings of 3D shapes.

In late 2007 several members of the graphics group, with help from local art instructors, conducted a study designed to investigate how artists' drawings of 3D shapes correlated with the mathematical properties of the shapes and known computer graphics line drawing techniques. The results of this study will be presented at SIGGRAPH 2008, and are available in full from this site.
