-------------------------------------
Summary: Investigate Norm Accuracy
Key: GEOMETRY-21
URL: https://issues.apache.org/jira/browse/GEOMETRY-21
Project: Apache Commons Geometry
Issue Type: Task
Reporter: Matt Juntunen
Based on discussion in GEOMETRY-17, we should investigate the floating point
accuracy of the current Vector normalization methods. Specifically, when the
UnitVector private subclass in Vector3D is implemented to return exactly 1.0,
the SphericalPolygonsSetTest#testGeographicalMap unit test in
commons-geometry-enclosing begins to fail. We should
# Determine the cause of this failure.
# Determine if the current approach with the UnitVector subclasses introduces
any issues with floating point accuracy.
# Add unit tests for Vector[123]D to quantify and verify the accuracy of the
normalization.
