Nonphotorealistic rendering techniques, including line
drawings, can be remarkably efficient at conveying shape
and meaning with a minimum of visual distraction. This
class will describe techniques for automated rendering of
3D models using a number of sparse line drawing styles, for
both artistic and illustrative purposes. We will
mathematically define lines such as silhouettes, contours,
creases, suggestive contours and highlights, and apparent
ridges and valleys. We then describe algorithms for
finding lines efficiently, including object- and
image-space methods, and discuss methods for stylization
and level-of-detail control. Finally, we provide a brief
introduction to concepts of visual perception, including
the information content of line drawings and the effects of
abstraction and detail on attention.
