if we realize the volume rendering througe the 2d texture slicing, do I need three copy along the axis(x,y,z)？<br><br><br><br></div><div class="im"><div></div><div></div><div></div>在 2013-05-24 22:21:35，"Aashish Chaudhary" <<a href="mailto:aashish.chaudhary@kitware.com" target="_blank">aashish.chaudhary@kitware.com</a>> 写道：<br>
