CGAL 6.0 - 2D Arrangements
|
A model of the concept ArrangementContractedLeftTraits_2 must be used when the parameter space of the surface, the arrangement is embedded on, is contracted on the left side and curves inserted into the arrangement are expected to reach this boundary side. A model of this concept can handle curves that reach the left boundary side when it is contracted.
