Subject [jira] [Commented] (MATH-1432) IndexOutOfBoundsException when calling PolygonsSet.getSize()
Date Wed, 10 Jan 2018 17:19:00 GMT

    [ https://issues.apache.org/jira/browse/MATH-1432?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16320672#comment-16320672
] 

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

bq. kind of help

After creating a repository, the first thing would be to move (and adapt) the code and unit
tests.
See e.g. what is being done in ["Commons Numbers"|https://git-wip-us.apache.org/repos/asf?p=commons-numbers.git]
(also split of "Commons Math").
Reviewing the API would also be nice.
If not done already, please subscribe to the "dev" ML; it will be necessary to coordinate
who does what.
Thanks!

>         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!
