I ported over some of my other Eclipse work and adapted it to VTK. It is pushed to my account on github and there is a writeup here: <a href="http://rkwright.github.io/geofx-pages/vtkview.html">http://rkwright.github.io/geofx-pages/vtkview.html</a>. There are 3 articles in there. The latest rev of the code is here: <a href="https://github.com/rkwright/vtkscene">https://github.com/rkwright/vtkscene</a> in the develop branch.</div><div><br></div><div>Mostly, it works great. However, when I tried the fifth cone example, which has the problematic vtkRenderWindowInteractor, I ran into similar problems as before. I instantiated it with a valid vtkPanel.RenderWindow but it still goes off into the ozone, sometimes crashing the native vtkOpenGL dylib.</div><div><br></div><div>I'm going to skip the interactor for now and move on to see if I run into more problems. If not, I can probably live without that widget but the problems there might be symptomatic of deeper problems on OSX 64 bit systems.</div><div><br></div><div>Any further suggestions would be welcome.</div><div><br></div><div>Thanks</div><div>Ric</div><div><br></div><div><br></div><span id="OLK_SRC_BODY_SECTION"><div style="font-family:Calibri; font-size:11pt; text-align:left; color:black; BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; PADDING-BOTTOM: 0in; PADDING-LEFT: 0in; PADDING-RIGHT: 0in; BORDER-TOP: #b5c4df 1pt solid; BORDER-RIGHT: medium none; PADDING-TOP: 3pt"><span style="font-weight:bold">From: </span> Sebastien Jourdain <<a href="mailto:sebastien.jourdain@kitware.com">sebastien.jourdain@kitware.com</a>><br><span style="font-weight:bold">Date: </span> Tuesday, August 6, 2013 8:56 AM<br><span style="font-weight:bold">To: </span> Ric Wright <<a href="mailto:rkwright@geofx.com">rkwright@geofx.com</a>><br><span style="font-weight:bold">Cc: </span> Sean McBride <<a href="mailto:sean@rogue-research.com">sean@rogue-research.com</a>>, vtkusers <<a href="mailto:vtkusers@vtk.org">vtkusers@vtk.org</a>><br><span style="font-weight:bold">Subject: </span> Re: [vtkusers] VTK6 and Java Cone Example 5<br></div><div><br></div><div dir="ltr">In Java you should use the Java specific classes anyway like vtkPanel/vtkCanvas or the new version of them used in the vtk.sample package of the vtk.jar...<div><br></div><div style="">The purpose of those example was to show the possible match between the different languages... </div><div style=""><br></div><div style="">Nothing more I believe,</div><div style=""><br></div><div style="">Seb</div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Tue, Aug 6, 2013 at 8:52 AM, Ric Wright <span dir="ltr"><<a href="mailto:rkwright@geofx.com" target="_blank">rkwright@geofx.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Ah, OK.

Should I file a bug? Just try to work around it by not using<br>
RenderWindowInteractors (sounds kind of lame). Or?<br><br>
Suggestions?<br><br>
