[vtkusers] Lookup table problem.

[Dongqing Chen]

Dear All:

    I have a question regarding vtkLookup table. Now, I want to visualize the polydata using only two colors. Each vertex is assigned one color just based on a criteria, which is a[i]>threshold or a[i]<threshold, where a[i] is an array associated with each vertex i. 

   I just looked through the lookup table, and was not familiar with the parameters. Would u please give me some hints on this?
  
Best Wishes,
