[vtk-developers] vtkLookupTable::Build

[Miller, James V (CRD)]

Just dug through the legacy system.  Looks like this "feature" was in the legacy system as well :)

There is logic in vtkLookupTable::Build() that prohibits a lookup table from recalculating its colors
if SetTableValue has been called. So its impossible to get a lookup table to recalculate if someone
has every modified the lookup table directly.
 
Searching back into the cvs log, it looks like this is way LookupTable has acted since it was called
vlLookupTable back in 1994.
 
Is this the desired behavior (now)?
 
I have an app where I want to have the lookup table calculate the appropriate colors, then I want to
modify a few of them.  Later on, I would to reset the values to the initial state.
