Subject: [vtkusers] How to reverse the colours to display contours.?


Hello,

When I display contours, I use the default vtkLookupTable() to represent the 
colour scheme. Default is min_value is red and max_value is blue.

Now what do I do in order to reverse it? I mean, min_value should be 
depicted with blue colour and max_value with red colour. Is there any way to 
do this?

Thanks

Regards
Rakesh Patil
