This allows to write to ostreams as std::cout or std::cerr, as well as to std::ostringstream and std::ofstream. The output operator is defined for all classes in the CGAL Kernel and for the class Color (see Section Colors) as well. Let os be an output stream. four points by sheraton jkia

WebAug 14, 2012 · I've had a very quick look at your code and ISTM that it'll only properly offset the simplest polygons. For example, I can't see any code to manage very acute convex angles where vertices can move exponential distances relative to the offset distance. Also, with acute concave angles with relatively short sides, there needs to be code to remove ...
