Dear vtk users,<br>
<br>
I'm try to use AddActor2D in my application but I always get a "<i>segmentation
fault</i>" when I do <b>ren1.AddActor2D(label.Actor)</b>.<br>
To be sure that this is not a bug in my code I've tried <u>annotatePick.tcl</u>
and <u>annotatePick.py</u> examples. The result has been same.<br>
Does someone knows about how to solve this which seems to be a vtk bug?<br>
<br>
Moreover, even OpenGL in installed on my machine, I feel my python
application running very slowly. I'm making an animation of 156
spheres (I do a <b>renWin.Render()</b> for each frame) with very low
resolution linked by line (tube was very very slow ...). <br>
I'm wondering whether this is normal or if there is a way to improve
it.<br>
Is it necessary to tell to vtk to use OpenGL? <br>
<br>
Thanks in advance,<br>
regards,<br>
<br>
Eric.<br>
