[vtkusers] scalar type conversion

[clyne at ncar.ucar.edu]

Are there any filters/utilities for doing scalar type conversion within
vtk? For example, I have a vtkImageData object with floating point data
that i'd like to volume render. Since the volume mappers in vtk don't
support floating point data I need to quantize the data to byte-sized
ints. Is there a facility for doing this? I'm using the tcl interface,
so doing it myself from the interpreter would obviously not be 
terribly efficient.

thanks - jc
