[vtkusers] negative volumes from vtkTetra.ComputeVolume

Hi,

We are estimating the volume of a solid which is constructed by delaunay3D filter. We used vtkmassproperties and vtkTetra.ComputeVolume.
We saw that vtkTetra.ComputeVolume gives negative volumes for some tetrahedrons. Should we take absolute value of those volumes? Why vtkTetra.ComputeVolume gives negative volumes?

Kind Regards,
