[vtkusers] Surface rendering of multiple objects

Hi Yanqiao,

I believe the only part missing is where I actually build the LUT with
useful colors:

        lut->SetTableValue(0,1.0,0.0,0.0);
        [...]
        lut->SetTableRange(0.0, 7.0);
        lut->Build();

You can find the complete example here (the one I used to produce the
image in the posting):

Hope this helps you.
 Christian
