[Paraview] Plotting a heightmap

[motes motes]

I have this very simple image file:

# vtk DataFile Version 3.0

The value of the above points correspponds to the intensity/height of
each pixel.

Is it possible to plot the above intensities as a heightmap (surface
in 3D)? Something like this:

when adding more points.
