Constraint-based modeling of three-dimensional shapes

Przemyslaw Prusinkiewicz and Dale Streibel


This paper shows that constraint-based modeling, so far perceived primarily as a graphics technique for man-machine interaction, also provides a viable method for the modeling of complex surfaces. The idea of constraint-based modeling of three-dimensional shapes is described and illustrated by examples. Difficulties related to the practical application of this idea are discussed, and methods for overcoming them are outlined. A potential of the constraint-based approach to the modeling of shapes found in nature is indicated.
