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.

Is there anyway to compute the dihedral angle for the edges in a PolyData?

I do not see a filter doing that directly.

This is a nice idea, I think you can move your post to the “Feature Request” category
