Boost geometry polygon outer

WebAt the moment it is a full-correct implementation, also correcting orientation, closing ring, removing invalid points. But i don't suggest integrating this, i think the self-intersecting removal is the only thing needed for boost geometry. I think also a function like this should be part of boost geometry, many projects can benefit from this. WebApr 9, 2014 · Boost.Geometry is an excellent geometric engine which can do many kinds of geometry computations with standard OGC defined geometries, it has good performance and reliablity, and it has an active and vibrant development community. ... Beyond that, BG assumes that a polygon consists of an outer ring object and an ‘inner rings’ object, …

WebPolygons are simple geometric objects (See also wiki but holes are allowed in Boost.Geometry polygons).; If the polygons underlying ring_type is defined as clockwise, the exterior ring must have the clockwise orientation, and any interior ring must be reversed w.r.t. the defined orientation (so: counter clockwise for clockwise exterior rings).
