<div>Hello Goodwin,</div>
<div> </div>
<div> thank you for your suggestions. Well, at the very end, I uninstalled everything Python-related on my PC and I installed the Enthought Python, the latest one announced today. Well, believe it or not, it's working :-)
</div>
<div>It's working also the vtkFloatArray(), exactly what I was doing before. The only changes I made (suggested by Prabhu Ramachandran on mayavi list) were to use scipy instead of numpy. </div>
<div>The only drawback of this installation is that is using Python 2.3.5 (while I had Python 2.4.2). However, if I can find somewhere a scipy version 0.3.3 for Python 2.4, I will try the same scripts on other machines that have Python
2.4.</div>
<div>After all the trial and error things I have tried, it may be possible that the bug is in Python 2.4.2.</div>
<div> </div>
<div>Thank you very much.</div>
<div> </div>
<div>Andrea.<br><br> </div>

<br>So long as your pipeline didn't cause any paging I don't think it would<br>cause a rendering performance hit though. Don't think you're doing<br>anything wrong though.<br><br>Goodwin<br><br>_______________________________________________
