Subject [jira] [Commented] (MATH-1432) IndexOutOfBoundsException when calling PolygonsSet.getSize()
Date Wed, 10 Jan 2018 14:57:01 GMT

    [ https://issues.apache.org/jira/browse/MATH-1432?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16320385#comment-16320385
] 

Gilles commented on MATH-1432:
------------------------------

bq. It looks like no new release is planned on 3.6.x branch, I guess you'll have to upgrade
to 4.0.

There are/have been discussions on the "dev" ML towards moving the contents of package {{org.apache.commons.math4.geometry}}
into its own component (i.e. "Commons Geometry").
Let us know if you'd be willing to help with the move (e.g. be a "beta-tester").

> Running the following code produces an IndexOutOfBoundsException:
>     public static void main(String[] args) {
>         List<Vector2D> vectors = new ArrayList<>();
>         vectors.add(new Vector2D(1, 1));
>         vectors.add(new Vector2D(1_189, 1));
>         vectors.add(new Vector2D(1_697_165, 147));
>         vectors.add(new Vector2D(1_592_444, 249_323));
>         vectors.add(new Vector2D(248_665, 110_887));
>         vectors.add(new Vector2D(37_142, 24_654));
>         vectors.add(new Vector2D(10_093, 8_137));
>         vectors.add(new Vector2D(966, 823));
>         vectors.add(new Vector2D(25, 25));
>         new MonotoneChain().generate(vectors).createRegion().getSize();
>     }
> Forgive the weird vector values!
