[vtkusers] Problem with surface reconstruction and contour filter in C++.

[Andrew J. P. Maclean]

I think what you said is pointing in the right direction. I have a
vtkDoubleArray where I read the intensity of each point into. If there
are no intensities, the values are set to 0. I then do a set points in
the vtkPolydata structure to this array.
The array is called (surprisingly!) "Intensity".
Could this array be interfering with the contouring?

Oh. Sorry, I only looked at the compile error. My first guess would be

  // Description:
  // If you want to contour by an arbitrary array, then set its name
here.
  // By default this in NULL and the filter will use the active scalar
array.
  vtkGetStringMacro(InputScalarsSelection);
  void SelectInputScalars(const char *fieldName)
    {this->SetInputScalarsSelection(fieldName);}

Try setting the scalar name to something appropriate and see if that
helps.
Could be somehow you're getting a different scalar name in your data
somehow
(and the contour filter isn't using it).
