[vtkusers] Color mapping 3d points cloud

[adrian C A]

Hi,

I have a cloud of 3d points that I read from file (each line stores de x y z coordinates) and save in a vtkPolyData using a vtkPoints. Next, using vtkDelaunay3d I achive to get the 3D rendering.
My problem is that I want to create a colorMapping that represents different heigh with different colour, but I don't know how set this scalar value (which, in this case, depends on the z variable).

Sorry if the question is very easy to solve but I am very newbie with VTK.

A lot of thanks, 

Adrian.
