LoPresti"" " Andrii Sydorchuk "The attached program uses boost::polygon to slice up a figure (with a ""hole"" cut out of it) into horizontal trapezoids. The output I get is: Output: polygon (4 3) (4 0) (0 0) (0 3) (4 3) ...which is clearly wrong. I am pretty sure my code is correct, because if I replace bg::HORIZONTAL with bg::VERTICAL, I get the correct output of a bunch of vertical trapezoids.
