Summary: Tessellator: Improve the election of diagonals when
splitting the polygon
Key: LUCENE-8775
URL: https://issues.apache.org/jira/browse/LUCENE-8775
Project: Lucene - Core
Issue Type: Bug
Reporter: Ignacio Vera
There are some cases when polygon tessellation fails and it seems it is due to
a bad election of the diagonal when splitting the polygon. Here I propose a
patch that make sure when splitting a polygon that the resulting polygons are
valid CW polygons.
In addition this patch adds few test to check the functionality of the
tessellator and throws an error if the polygon cannot be splitted instead of
just empty the current tessellation.
