areEquivalentPrincipalAxes MethodStatic

Test for match among selected members as they exist after inertiaProductsToPrincipalAxes.

• The members considered are:
  • origin of local to world map (i.e. centroid),
  • radius of gyration,
  • axes of localToWorldMap.
• Axis direction tests allow these quirks:
  • opposite orientation is considered matched.
• Full xyz symmetry: If x,y,z radii are matched, axes are not tested.
• Symmetry in xy plane: If x and y radii are matched, the x and y axes area allowed to spin freely. Only Z direction is tested.
• If either or both are undefined, returns false.
