<DIV >hello Peter Spring,</DIV>
<DIV> Is that you want to use vtkPolyDataReader to read vtk file and display it?</DIV>
<DIV>I have a sample code and my outputs just black-white colors.</DIV>
<DIV>But you need to write to your codes.I just convert is into java.I did not have tcl or other language's code.</DIV>
<DIV>here it is:</DIV>

Goodday, and merry christmas.
i have met some problem when i generating some vtk binary data using
vtkPolyDataWrite.
what i did was using Dicom reader to read a set of dicom files and
construction iso surface after that i use vtkPolyDataWriter to save
the data to be vtk binary. things can be conducted perfectly but one
problem bothers me is the coloring.
when i read the generated vtk binary data, the data is shown with some
color. it is very strange because i did not assign any color when i
previously do the iso surface construction. and i notice that
different iso value has different color.... for the vtk binary data.
can someone help me on this issue since i do not want any color on the
vtk binary data.
thanks very much...
Yours
P.
