[vtkusers] How to set different color to each point

[Gwenaël Guillard]

Hi,

You have to use

yourPolydata->GetPointData()->SetScalars(yourArray);
youPolyDataMapper->ScalarVisibiltyOn();
youPolyDataMapper->SetScalarModeToUsePointData();

Verfiy that the index of your array corresponds with the index of polydata points.

HTH, Gwen
