Ian Perera created MATH-1060:
--------------------------------
Summary: MathInternalError when calculating barycenter of
PolyhedronsSet
Key: MATH-1060
URL: https://issues.apache.org/jira/browse/MATH-1060
Project: Commons Math
Issue Type: Bug
Affects Versions: 3.2
Environment: Ubuntu, Java 1.7.0
Reporter: Ian Perera
I'm not sure if I could replicate this well enough to be useful - I am trying
to construct a PolyhedronsSet from a collection of Planes using
RegionFactory.buildConvex(). The input planes are created from running QHull -
I don't have the actual normals but I can add them to this report if I run into
this again.
