Oops. My bad. I'll make a note not to try to be helpful so early in the morning 8-O I end up causing more trouble.... :-P double xdiff = x1-x2; double ydiff = y1-y2; double zdiff = z1-z2; double d = Math.sqrt(xdiff*xdiff + ydiff*ydiff + zdiff*zdiff); Simeon =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
