Boolean operations on polygons are a set of Boolean operations (AND, OR, NOT, XOR, ...) operating on one or more sets of polygons in computer graphics. These sets of operations are widely used in computer graphics, CAD, and in EDA (in integrated circuit physical design and verification software). Webabout boolean operation on conic polygons, they presented an O(M∗ N) time algorithm, where M and N are the number of edges (or arcs) in the two conic polygons. In theory, circular-arc polygon is a special case of conic polygon, the previous method indeed can deal with boolean operation on circular-arc polygons. How-
