<br>
Thanks.<br>
<br>
Ken, let me ask you another question please, it might help me solving my<br>
empty rendering window.<br>
<br>
I notice when I animate my vtkAppendFilter in a continuous loop it works<br>
fine in old vtk version but in the new version, it will animate only one<br>
loop then the render window becomes empty like when I render two actors. I<br>
tried to zoom to fit but no luck.<br>
<br>
What is interesting is in new vtk if in each animation step I delete the<br>
filter and recreate the scene again, it will loop without a problem and the<br>
model is always visible in the render window!!<br>
<br>
it looks like that vtkAppendFilter get corrupted after finishing one loop<br>
witch it causes the model to disappear from the render window!! any clue why<br>
this behaviour in new vtk?<br>
<br>
