<DIV>Dear RTK users,</DIV>
<DIV> </DIV>
<DIV>In this example:</DIV>
<DIV><A title=http://wiki.openrtk.org/index.php/RTK/Scripts/DrawGeometricPhantom
href="http://wiki.openrtk.org/index.php/RTK/Scripts/DrawGeometricPhantom">http://wiki.openrtk.org/index.php/RTK/Scripts/DrawGeometricPhantom</A></DIV>
<DIV> </DIV>
<DIV>How can I get a cone phantom instead of a hyperboloid?</DIV>
<DIV>If I use the file on the wiki page and the default file and rtk
application. I get a hyperboloid instead of a cone as the picture in the
wiki.</DIV>
<DIV>Is there a way to change all the coefficients of the equations describing a
quadric surface?</DIV>
<DIV> </DIV>
<DIV>Best regards,</DIV>
<DIV>Louie</DIV></DIV></DIV></BODY></HTML>
