[vtkusers] Some Help for a vtk beginner!

[Adrien Brunet]

Hi guys,

I hope this has not been already asked but the archives are not really 
handy to explore...

I'm converting stl files from ascii to binary and from binary to ascii 
with vtk. I use the following code:

#!/usr/bin/env python

import vtk


def convert_stl2ascii(path):
     reader = vtk.vtkSTLReader()

     reader.SetFileName(path)
     reader.Update()
     write = vtk.vtkSTLWriter()
     write.SetFileTypeToASCII()

     write.SetInput(reader.GetOutput())
     write.SetFileName(path)
     write.Write()


def convert_stl2binary(path):
     reader = vtk.vtkSTLReader()

     reader.SetFileName(path)
     reader.Update()
     write = vtk.vtkSTLWriter()
     write.SetFileTypeToBinary()

     write.SetFileName('_binary.stl'.join(path.split('.stl')))
     write.SetInput(reader.GetOutput())
     write.Write()



It does work BUT, Let's say I have a ascii stl file like this:

|solid first_name
     [...]
endsolid
solid second_name
     [...]
endsolid|

I can convert it to a binary file but when I try to convert it back to 
ascii, I get something like:

|solid ascii
     [...]
endsolid|

What should I do to keep the Region name first_name and second_name and 
to avoid that several different regions to be merged in only one region?

Cheers !!
