3D ruler on non output 0 of a filter
Issue:
- When measuring a point cloud of an non-output port 0. (e.g Trajectory output of the slam), the ruler doesn't find the point.
- This issue seems to come from paraview
vtkSMRenderViewProxy::ConvertDisplayToPointOnSurface
, where they only test on the first output port.
Work around:
- Extract the point with an other filter to use the output port 0 (e.g select the points, do an extract selection, measure on this extraction)
