Summary0000571: Quadratic Wedge + vtkProbeFilter
DescriptionvtkProbeFilter 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.

 John send me this email:

I have temporarily got around the problem of null point Id’s in the boundary by the following hack

int vtkQuadraticHexahedron::CellBoundary(int subId, double pcoords[3], vtkIdList *pts)
{
   // Copy the point Id's of the corners to the linear hex.

   for ( int i = 0; i < 8; i++ )

      this->Hex->PointIds->SetId( i, this->PointIds->GetId(i) );
  return this->Hex->CellBoundary(subId, pcoords, pts);
}

but as I think I mentioned earlier, ‘pts’ is missing the mid-side nodes of the face.
