<DIV><FONT face=Arial size=2>Dear All:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> I have a question regarding
vtkLookup table. Now, I want to visualize the polydata using only two
colors. Each vertex is assigned one color just based on a criteria,
which is a[i]>threshold or a[i]<threshold, where a[i] is an
array associated with each vertex i. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2> I just looked through
the lookup table, and was not familiar with the parameters. Would u
please give me some hints on this?</FONT></DIV>
