WebFor a polygon, the Maximum Lengthparameter specifies the perimeter of the smaller polygon created by the self-intersection. Only those segments with a length or perimeter smaller than the specified maximum length will be removed or split. WebOne of the important intersection questions is whether a closed polygonal chain de nes the edges of a simple polygon. The problem reduces to detecting whether the chain is self-intersecting. This problem can be solved e ciently by supposing that the polygonal chain is a simple polygon, attempting to triangulate the polygon, and add computer to a canon scanner
