Boolean operations on conic polygons
WebConic Polygons: Regularized boolean operations on straight-lineor conic polygons can be built on top of the sweep-linealgorithm for segment intersection, see [21, Section 10.8]. The corresponding data structure in LEDAis called generalized polygons. We reused it with only one small change.

WebFor two simple polygons Aand B, the boolean operations are defined: [Intersection test] of two polygons (CGAL_do_intersect(A,B)): This checks if the two polygons Aand Bdo intersect without computing the intersection area. It returns trueif the polygons Aand Bdo intersect, otherwise falsewill be returned.
WebBoolean operations combine any set of shape layers through one of four formulas: union, subtract, intersect, and exclude. Boolean groups are treated as a single shape layer and share fill and stroke properties and can be combined with other boolean groups through subsequent boolean operations.
