vtkLogLookupTable - map scalar values into colors using logarithmic (base 10) color table
Super Class: vtkLookupTable
Description:
vtkLogLookupTable is an object that is used by mapper objects to map scalar values into rgba (red-green-blue-alpha transparency) color specification, or rgba into scalar values. The difference between this class and its superclass vtkLookupTable is that this class performs scalar mapping based on a logarithmic lookup process. (Uses log base 10.) If non-positive ranges are encountered, then they are converted to positive values using absolute value.
