Although the lecturer said he knew a great deal about this function from the point of view of calculus and linear algebra, he regretted that he could not visualize its geometric shape. I thought our graphics team could help him out. I telephoned my sophomore assistant, Ed Chang ‘91, who rendered the surface on a computer using a contour-surface algorithm developed by Steve Ritter ‘85 and Kevin Pickhardt ‘85 in Professor Andries van Dam’s computer-graphics course.
