ABSTRACT:
Computer-aided method and apparatus for defining surfaces of a three-dimensional object on the basis of a three-dimensional wire-frame model, wherein a plurality of pairs of edges selected from edges which constitute the three-dimensional wire-frame model are sequentially pointed, each pointed pair consisting of two edges lying on the same plane, and a group of candidate edges is determined, the group consisting of the currently pointed pair of edges and at least one edge lying on the same plane as the edges of the currently pointed pair, so that those candidate edges of the determined group which cooperate to define a closed loop are determined as a set of closed-loop defining edges, and a surface of the three-dimensional object is defined on the basis of the set of closed-loop defining edges.
