I'll take a look. BTW, none of the examples in Examples/Infovis/Java work either:</div><ul><li>HelloWorld.java draws some simple tree in B&W then crashes with the same threading error.</li><li>Trees.java works, but doesn't do anything. Simple white cross on the screen but nothing else. Not sure what it is SUPPOSED to do, but no tree appears that's for sure.</li><li>InfoVis.java won't compile because several breadthfirst.* methods can't be found.</li></ul><div>I'll keep poking, but I'm getting the sense that Java is a neglected child in the VTK world. Is it really used by any part of the VTK community? If so, who?</div><div><br></div><div>I wrote up my first impressions of VTK on my (little-used) blog.</div><div><br></div><div><a href="http://blogs.geofx.com">http://blogs.geofx.com</a>/</div><div><br></div><div>So my dilemma is continue to try to make VTK work (which will be a formidable learning curve, apparently) or go back to incrementally improving GMS, which I know DOES work. I'd rather use VTK, but don't want to tilt at windmills. So if I knew (and could exchange ideas) with others actually using Java and VTK for real work, I'd be a lot more confident.</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.
