Subject [jira] [Updated] (MATH-1447) PolygonsSet does not handle intersecting infinite lines
Date Fri, 02 Feb 2018 15:07:00 GMT

     [ https://issues.apache.org/jira/browse/MATH-1447?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gilles updated MATH-1447:
-------------------------
    Description: 
When created from boundaries consisting of two intersecting infinite lines, PolygonsSet.getVertices()
throws an IndexOutOfBoundsException.

{{Ex:}}
 {{Line line1 = new Line(new Cartesian2D(0, 0), new Cartesian2D(1, 1), 1e-10);}}
 {{Line line2 = new Line(new Cartesian2D(1, -1), new Cartesian2D(0, 0), 1e-10);}}

{{List<SubHyperplane<Euclidean2D>> boundaries = new ArrayList<>();}}
 {{boundaries.add(line1.wholeHyperplane());}}
 {{boundaries.add(line2.wholeHyperplane());}}

{{PolygonsSet poly = new PolygonsSet(boundaries, 1e-10);}}

{{poly.getVertices(); // throws exception}}
