ABSTRACT:
Elements of a three-dimensional object having a plurality of flat polygonal surfaces are constructed by providing a visual model of the object and constructing a graph from the visual model. The graph illustrates a plurality of nodes connected by lines. Each node represents one of the polygonal surfaces, and each line connecting the nodes corresponds to an edge of the visual model located between corresponding polygonal surfaces. One of the nodes is selected as a starting node, and the graph is traversed beginning at the starting node. The traversal continues by successively traveling from previously selected nodes to previously unselected nodes along the lines without selecting any node more than once. The elements are constructed by drawing a corresponding polygon for each node as the nodes are selected.
