[vtkusers] Using filters

[Arun Nagarajan]

Ah, ok. That makes more sense. Another question. In the man page for
ImageToPolyDataFilter class, there is a note saying:

The input linear lookup table must be of the form of 3-component unsigned
char

What exactly is a 3-component unsigned char?

Thanks.

Arun
