Message:

Added getConnections() to SphericalPointDistribution.

  • we use tesselation in order to extract the connection information between nearest neighboring points from the BoundaryLines of the tesselation. The triangles are ideal as they assure that no point lies within a triangle, hence all these points may be safely combined.
  • functions reside in extra module as with get().
  • added extensive unit tests.
  • TESTS: Removed XFAIL from SphericalPointDistributionUnitTest.
