[vtkusers] Read Rectilineargrid File::Only the grid is visible

[Winfried Bilgic]

Hello Folks, 

i tried many things but i was still unable to read an vector dataset from an rectilinear gridfile. What i get from the file is the visualization of the grid, but no surface. I bet the solution is easy, but with 11 hours working in my neck i need your helpful assistence.

Thanks in advance and kind regards Winne
