hasNarrowConcaveAngleWW method

bool hasNarrowConcaveAngleWW()

Tests whether the input has a narrow concave angle (relative to the offset distance). In this case the generated offset curve will contain self-intersections and heuristic closing segments. This is expected behaviour in the case of Buffer curves. For pure Offset Curves, the output needs to be further treated before it can be used.

@return true if the input has a narrow concave angle

Implementation

bool hasNarrowConcaveAngleWW() {
  return _hasNarrowConcaveAngle;
