Réf:Re: [vtkusers] Scalar color / LookupTable / Interpolatio

[Jacques Charreyron-F264897]

Hello,

I really think so, but is it avalaible in vtk 4.4.latest ?. I have downloaded
and it does not compile  ( method not found in vtkMapper). I can not use cvs
because of our hot firewall ... I have tried a limited manual update ... To be
continued....

Jacques,

     Is this what you are looking for ?

  currentMapper->SetInterpolateScalarsBeforeMapping(1);

     Thanks for providing code, it is always easier to understand the
 problem.
