This paper builds on principles of depicting transparency in hand-made line drawings and develops a method to generate similar but computer-generated line drawings in a two-step process. In the first step a brightness image is generated which is used as a basis for the line drawing created in the second step. Three different methods derived from traditional drawing techniques are shown.
