Abstract : We first pose the following problem: To develop a program which takes line- drawings as input and constructs three-dimensional objects as output; such that output objects are the same as the ones we see when we look at the input line-drawing. We introduce the principle of minimum standard-deviation of angles (MSDA)and discuss a program based on MSDA. We present the results of testing this program with a variety of line-drawings and show that the problem constitutes a solution to the stated problem over the range of line-drawings tested. Finally, we relate this work to its historical antecedents in the psychological and computer-vision literature.
