<HTML><BODY STYLE="font:10pt verdana; border:none;"><DIV>dear vtk users,</DIV> <DIV> I want to render CT volume data. Most of my codes are the copy of the example "SimpleRayCast.tcl" except that I use vtkVolume16Reader to read in the CT slices, which are raw data of 16 bits pixels. I really appreciate your suggestions. Thank you.</DIV> <DIV> </DIV></BODY></HTML><br clear=all><hr>从网站得到更多信息。MSN Explorer 免费下载：<a href='http://explorer.msn.com/lccn'>http://explorer.msn.com/lccn</a><br></p>
