I have a surface mesh made of triangle cells. I would like to compute the dihedral angle for each edge in the mesh.

I have found the FeatureEdge filter, which must be computing the dihedral angle, but I haven’t find any way to expose that angle, or any other filter that can provide this information.

Apparently, there is no filter to extract the dihedral angle.  
Is it possible to rework the FeatureEdge filter or add a new DihedralAngleFilter that gives the angle per edge?

Hi @Juan_Jose_Casafranca

It looks like you wanted to create a feature request, however you did not reformulate your post into a feature request, do you think you can do that ?
