I have a 128^3 volume that i'm trying to volume render. The images I get are truly stunning, good job here guys.<br>
<br>
I've written a script to rotate the volume rendering from 0 to 180
degrees, in 2 degree increments. But every time I cross the
45degree mark on any axis, it crashes with a segmentation fault.<br>
<br>
a Backtrace shows the following:<br>

This looks like a VTK bug to me. I've tried it with 15 different
datasets from the same project (same dimensions, etc), and all show the
same behavior.<br>
