I have a VTK object with different colors for each point according to the point value. I want to add options to allow the user to view the same object with different values, with different colors for each value. I am using a VTK ColorLookupTable for this.
For example, if the user selects pressure (from a set of options) the values of the object that are relevant to pressure will be shown with the colors.
Is this possible, to add options and change the values, with VTK?

Sure, that is exactly what a vtkLookupTable is for.

You just need to use Set*Range (e.g. SetValueRange, etc.) to setup your new color scheme.
