[vtkusers] How to calculate the angle of an edge?

[lynx.abraxas at freenet.de]

Hello!


One other problem I have:
How  can  I  calculate  the  angle  of  an edge (eg. the angle between the two
points/vertices of a mesh and the origin of the coordinate system)?
I want to do that for a complete mesh. Sadly vtkMeshQuality has  no  qualities
for  edges.  Is  there any other class in vtk to use or would I have to do the
calculation on my own?

Thanks again for any help or hints.
