[vtkusers] How to visualize a smooth colored density map from 2d histogram?

[Mario Emmenlauer]

Dear All,

I have a 2D histogram of discrete events. I'd like to visualize
this as a false-color-coded smooth "height profile". Is there something
existing in VTK that I could use to smoothen (fit a 2D function?) to the
histogram, and then translate height into a color lookup table?

Thanks for any pointers/ideas! All the best,
