[vtkusers] Coloring 2D surface along contourlines

[Deij, Menno]

I’ve solved this problem by adding a vtkLookupTable with a fixed number of colors to the vtkPolyDataMapper and by calling InterpolateScalarsBeforeMappingOn() on the mapper. Now the picture looks as attached. Without a color range as specified by the vktLookupTable you get the original picture with blocky shapes.

Thanks for your help, loading the vtkStructuredGrid data into ParaView helped pinpointing the problem: the absence of a lookup table for colors and enabling interpolation of scalars on the mapper.

Best wishes,


Menno Deij
