holes share are connected to the same vertex
Ignacio Vera created LUCENE-9417:
------------------------------------
Summary: Tessellator might fail when several holes share are connected to the same vertex
Key: LUCENE-9417
URL: https://issues.apache.org/jira/browse/LUCENE-9417
Project: Lucene - Core
Issue Type: Bug
Reporter: Ignacio Vera
Attachments: image-2020-06-25-11-03-02-075.png, image-2020-06-25-11-05-50-406.png
Related to LUCENE-9400, tessellator might fail when several polygons are connected to the same polygon vertex, and this vertex is connected from more than one segment. For example the following polygon:
!image-2020-06-25-11-03-02-075.png|width=377,height=232!
Holes get connected the following way:
!image-2020-06-25-11-05-50-406.png|width=357,height=236!
Two holes are connected to the same point, and this point is shared across different segments. We need to make sure we connect in such a way that we are not crossing each other.
