[vtkusers] vtk 4.4.2 vs. 5.0.x differences

[Bernd Speiser]

Hi all,

we are using vtk for a lerger electrochemical simulation project
within a Qt 3 GUI. The software package was originally implemented with 
vtk 4.4.2.
Rcecently we have switched some of our computers to openSuSE 10.3 and 
re-installed vtk. This time we downloaded vtk 5.0.2. Compilation works 
ok, but when we run the program on these recent systems, no graphs 
appear on the screen (the Qt GUI is apparently ok). Installing in 
parallel vtk 4.4.2 and recompiling produces an executable which works 
fine - showing all the intended graphics. So, our conclusion is that 
something important for our application does seem to have changed during 
the evolution of vtk from 4.4.2 to 5.0.2.
I have been searching within the vtk web site for a file describing the 
differences between vtk 4.4.2 (or other older versions) and 5.0.x. 
However, I did not find any appropriate information. Does someone have a 
link to such information?
Also, has someone experienced similar problems and could give me a hint 
as to where to check the code?

Best regards
Bernd
