VTK with MangledMesa isn't that bad, actually. I've done it several times on our SGI Irix machines here several times.<br>
<br>
Sadly, I wasn't able to get the vtkXOpenGLOffScreenRenderWindow class
to work at all . And, of course, it requires OpenGL graphics
hardware which eliminates alot of our systems in-house. <br>
<br>
If desired, I could write up instructions on how to get VTK & Mesa
6.2.1 to play nice together (On Irix at least, I imagine it's very
similar for other systems)<br><br><div><span class="gmail_quote">On 5/12/05, <b class="gmail_sendername">tom fogal</b> <<a href="mailto:tfogal@apollo.sr.unh.edu">tfogal@apollo.sr.unh.edu</a>> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
