Find the intersection between sources

I have two sources, and I apply transformations to them. I want to find the distance to the point of convergence. Is there a way to do that? Or get the coordinates of the intersection of the two sources?

Ruler source let you compute distance.
You can’t compute the intersection within ParaView but , if you are a developper, it can be done with vtkbool :
or with the vtkBooleanOperationPolyDataFilter
