<div dir="ltr"><div><div>Hi,<br></div>OffsetZ probably refers to the coordinate of the volume in the room coordinate which we don't use in RTK. Everything is set in the tomography coordinate during reconstruction. You can always change the coordinates of your volume after if you want to put it in some other coordinate system.<br></div>Simon<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Jul 13, 2015 at 10:38 AM, Guangming Zang <span dir="ltr"><<a href="mailto:guangming.zang@kaust.edu.sa" target="_blank">guangming.zang@kaust.edu.sa</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-family:'trebuchet ms',sans-serif;color:rgb(0,0,255)">problem fixed.</div><div class="gmail_default" style="font-family:'trebuchet ms',sans-serif;color:rgb(0,0,255)">because the scanned object is symmetric and i did not notice that i should -Z axis in scanner to map Z in RTK</div><div class="gmail_default" style="font-family:'trebuchet ms',sans-serif;color:rgb(0,0,255)">thanks.</div><div class="gmail_default" style="font-family:'trebuchet ms',sans-serif;color:rgb(0,0,255)">but, i still do not know in RTK how to show the <span style="font-size:14px">OffsetZ.. :(</span></div><span class="HOEnZb"><font color="#888888"><div class="gmail_default" style="font-family:'trebuchet ms',sans-serif;color:rgb(0,0,255)"><span style="font-size:14px"><br></span></div><div class="gmail_default" style="font-family:'trebuchet ms',sans-serif;color:rgb(0,0,255)"><span style="font-size:14px">Guangming</span></div><div class="gmail_default" style="font-family:'trebuchet ms',sans-serif;color:rgb(0,0,255)"><span style="font-size:14px"><br></span></div></font></span></div><div class="gmail_extra"><span class=""><br clear="all"><div><div><div dir="ltr"><div><div dir="ltr"><font style="line-height:23.32400131225586px" face="arial, helvetica, sans-serif" color="#674ea7"><b><i>Guangming Zang (Alex)</i></b></font><div style="line-height:23.32400131225586px"><font face="arial, helvetica, sans-serif"><b><i><font color="#0b5394">King Abdullah University of Science and Technology</font><font color="#073763">(KAUST)</font></i></b></font></div><div style="line-height:23.32400131225586px"><span style="font-family:arial;font-size:13px;line-height:20.020000457763672px"><font color="#0b5394"><b><i>University of Chinese Academy of Sciences(UCAS)</i></b></font></span><font face="arial, helvetica, sans-serif"><b><i><font color="#073763"><br></font></i></b></font></div><div style="line-height:23.32400131225586px"><span style="font-family:arial;font-size:13px;line-height:20.020000457763672px"><font color="#0b5394"><b><i><br></i></b></font></span></div><div style="line-height:23.32400131225586px"><span style="font-family:arial;font-size:13px;line-height:20.020000457763672px"><font color="#0b5394"><b><i><br></i></b></font></span></div><div style="line-height:23.32400131225586px"><br></div></div></div></div></div></div>
