[vtkusers] rendering isosurface and crashing

[dsjen at cs.unc.edu]

Hi Jeff,

My use of vtkCanvas is has-a.  The program does consistently crashes 
when I load a large number of images (but works fine with a smaller 
set), when trying to view an isosurface.  However, using volume 
rendering techniques, such as maximum intensity projection, the 
rendering is slow, but at least doesn't crash die with an 
EXCEPTION_ACCESS_VIOLATION.

As for code that causes it to crash, I'm not sure which code segment 
is causing it to crash.  Are you thinking that it's somewhere with 
vtkCanvas?

I will updating my version of Java and see if that fixes the problem 
though.

Thanks,
Dennis
