Quadratic Wedge + vtkProbeFilter
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
vtkProbeFilter sometimes fails to find the cell containing a point on a line probe. This occurs when the point is not in the first cell connected to the closest point id and the walking scheme is used in vtkPointSet::FindCell().
I think there is a problem in vtkQuadraticWedge::CellBoundary(). The call cell->CellBoundary()( from vtkPointSet::FindCell())returns a list of null point id’s for the closest plane. This is because the instance of the linear wedge in vtkQuadraticWedge has null point id’s also :-(
Use of the linear wedge CellBoundary() method will only give the corner nodes on the closest plane and not the mid-side nodes. I am not sure if GetCellNeighbors() will work on this reduced topology.
