[vtkusers] Modifying Curve Properties in vtk

[Alark Joshi]

Hi,

I want to be able to modulate the thickness of the splines as they get 
longer. I observed the Kochanek/Cardinal splines pass data to the 
PolyDataMapper that draws them. One needs to specify the thickness and other 
attributes of the curve before the data is passed to PolyDataMapper.

Is there any other way that I can draw curves and modulate their properties 
like color/thickness as the curves get longer? I wanted to ask before I 
wrote my own classes to do it. Ayn help would be greatly apprecaited. 
Thanks.

Regards,

Alark
