------------------------------------
Summary: Checks for coplanarity when creating polygons shows
numerical issues
Key: LUCENE-8140
URL: https://issues.apache.org/jira/browse/LUCENE-8140
Project: Lucene - Core
Issue Type: Bug
Components: modules/spatial3d
Reporter: Ignacio Vera
Coplanarity checks in GeoPolygonFactory shows numerical errors when the
distance between two points is very small compared to the distance of the other
two points. The situation is as follows:
Having three points A, B, & C and the distance between A & B is very small
compared to the distance between A & C, then the plane AC contains all points
(co-planar) but the plane defined by AB does not contain C because of numerical
issues. This situation makes some polygons fail to build.
