[vtkusers] Color a surface

[Gerrick Bivins]

Hi Nens,

If you set a lookup table on a mapper it will map scalar data to colors for you.



I think instead of "// Generate the colors for each point based on the color map"

You just need to create a vtkDoubleArray of your z values (or which ever coordinate you are using for elevation).

Set this as the scalars of you point data and get rid of the "colors" array.



This example has per cell coloring but gives an idea:

Hi Nens could you send a complete code, sufficient to reproduce your problem?
