Thanks Christian,<br><br>I will check the differences carefully to find out what I might have mistaken.<br> <br>By the way, do you have any idea of ways to rendering single voxels. My case is tha one of the label only corresponds to a few separate voxels, which cannot even form a surface, while some other labels corresponds to a lot of connected voxels. It seems for the latter ones, surface should be used for rendering purpose. But for the former one, surface may not be a good choice. I am trying to find ways to combine them together. Any suggestions?<br>

<div class='shrinkable-quote'><br>>
<br>> I downloaded the code and data you provided in the previous post and changed
<br>> the code as you told in this post by adding lut->SetTableRange(0.0, 7.0);
<br>> and changed mapper->SetScalarModeToUsePointData(); to
<br>> mapper->SetScalarModeToUseCellData(); But what I get after running the
<br>> program is shown in the image

<br>> from your result. So I am wondering maybe something is wrong. Could please
<br>> check it. The source code is also attached.
<br>>
<br>> Thanks very much!
<br>> Best,
