Bounding Box of PolyCirculinearCurve2D

[Herbert Roider]

Hi,
if i convert a line to a PolyCirculinearCurve2D and create the bounding Box the result is wrong in my opinion:

LinkedList<CirculinearElement2D> line = new LinkedList<>();
line.add(new LineSegment2D(new Point2D(5,1), new Point2D(-7,2)));
PolyCirculinearCurve2D curv = new PolyCirculinearCurve2D(line);
Box2D b_box = curv.boundingBox();
System.out.println("Boundingbox: "  + b_box.toString());

result:
Boundingbox: Box2D(5.0,4.9E-324,1.0,2.0)

or with 2 elements:

LinkedList<CirculinearElement2D> line = new LinkedList<>();
line.add(new LineSegment2D(new Point2D(-1,3), new Point2D(-2,1)));
line.add(new LineSegment2D(new Point2D(-2,1), new Point2D(-3,3)));      
PolyCirculinearCurve2D curv = new PolyCirculinearCurve2D(line);
Box2D b_box = curv.boundingBox();
System.out.println("Boundingbox: "  + b_box.toString());

result:
Boundingbox: Box2D(-2.0,4.9E-324,1.0,3.0)

In my project the PolyCirculinearCurve2D contains lines and arcs. It is the toolpath for a CNC lathe.
I use this library in a netbeans plugin to plot a G-code contour. It is mainly used to calculate intersections between circles and lines.

Complex because of a lot of java interfaces, but does a very good job, thank you!

Hi,
sorry for delay of response, I have actually moved the repository to GitHub, and do not visit sourceforge as regularly...
You are right, this is a bug.
I fixed the problem, you can updated source from this page: https://github.com/dlegland/javaGeom
or you can wait for next release (not yet planned, however).

hope this helps anyway...
regards,
David
