</span>Intersecting volume would a be problem but having multiple volume<br>

would be a real problem for us. We are doing x-ray tomography of drill
cores. The core breaks into pieces during drilling, so think of each
volume I'm speaking of as one of the pieces in the attached photo. Our
software will do some algorithmic "puzzling" to align the volumes
(pieces) after scanning, but we need to have an interactive way for the
user to manually align the pieces as well, for the cases where automatic
alignment fails (which it will in some hard/hopeless cases).<br><br></div><div>If
VTK can't properly render intersecting volumes, then I'm afraid it will
be really hard to make such a tool for manual alignment intuitive to
use. The user must be able to see the pieces while rotating them when
they are close together, which invariably means they will intersect now
and then as he/she tries to fit them together.<br><br></div></span><div><span>Is this
limitation of VTK present also in 7.0? I've been thinking of compiling a
custom VTK 7.0, since I saw it has many improvements to volume
rendering, and if it can do composite rendering of intersecting volumes,
then we'll definitely do that.</span><div><div><img src="https://ssl.gstatic.com/ui/v1/icons/mail/images/cleardot.gif"></div></div><span><font color="#888888"><span><font color="#888888"></font></span></font></span></div><span><font color="#888888"><span><font color="#888888"><div>Elvis<br></div></font></span> </font></span></div><span><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
