You could trace curves around your object in a few planes to
define a surface and use that surface to mask the map. Or you
could try a watershed segmentation mouse mode. What works
depends on characteristics of the actual data. Videos showing
these two techniques are on the Chimera web site under video
tutorials:<br>

<div><font color="#000000" face="宋体" size="3">Dear all,</font></div>
<div><font color="#000000" size="3">We want to color our EM
density map , so we need mask different part of the map in
order to distinguish them with different colors.
Unfortunately, the sample is not irregular shape , we could
not use "shape" to mask volume as usually. Could anyone give
some suggestion?</font></div>
<div> </div>
<div><font color="#000000" size="3">We also use Amira for 3D
rendering. We think the rendering in amira is just the mask,
so we want solve the problem the mask the irregular shape
with amira , have anyone done with it?</font></div>
