[vtkusers] Question about coloring special parts of Data

[Daniel Zuidinga]

Hello vtkUsers,

i created a surface by  feeding a vtkPolyData-Object with vtkPoints and 
vtkCellArrays. In addition i render it to the Screen with the help of a 
vtkPolyDataMapper and an vtkActor.
So i can manipulate the representation - for example the color - by 
manipulating the Actor.

My problem is now, that i only want to colorize some special Points of 
the Data to one other color. How can i achieve this?

Of course i can create a second vtkPolyData a second vtkMapper and a 
second vtkActor-Object, but i don´t think that this is a good solution.

Regards
Daniel
