However, when I get adventurous and try to modify the code, things just don't work out as well. I'm trying to import a stack of TIFF files, build isocontours, then output the contours as an STL file. To start with, I tried just inserting the following code into the Medical2.cxx example in place of the V16 code.</SPAN></FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px;

It doesn't go back to my unix prompt. No error messages, nothing. Is there an example anywhere of a functional program that loads TIFF files and generates some sort of feedback. It would be great if such an example had an associated Tiff stack known to work with it. I'm running a Mac G4, OSX 10.4, 1.5 gBytes of RAM and VTK 4.4. The side of my head is getting flat from banging it against the wall - any help will be appreciated.</SPAN></FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" face="Monaco" size="2"><SPAN class="Apple-style-span" style="font-size: 10px;">Corrie</SPAN></FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" face="Monaco" size="2"><SPAN class="Apple-style-span" style="font-size: 10px;"><BR class="khtml-block-placeholder"></SPAN></FONT></DIV><BR><DIV> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Corrie Allen, Ph.D.</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Lone Wolf Bioscience</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica"><A href="mailto:lonewolfbiosci@verizon.net">lonewolfbiosci@verizon.net</A></FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><BR class="khtml-block-placeholder"></P> </DIV><BR></BODY></HTML>
