Amira/Avizo document their mesh format rather well in the help. It is
different depending on the data type stored.
If you're a moderately skilled coder you could write a piece of code to do
the conversion.
My lab has done this with a few formats using matlab to write our code in.
Perl code could do it to, several of the amira mesh types are plain text
which perl excels at.

Thank you for your promt reply. I am totally new to the volume rendering. I
don't know if it is a volume data set. All those numbers after @1 represent
the electron density values. It is a 3D scalar fields defined on a uniform
grid. I will try the obj format. But I have almost 200 am files, so I really
want to convert them to another type of file by keeping those data after @1
and only changing the head.
Regards,
-Hui

Is an "AmiraMesh" file actually a mesh? If so, you want to export to
OBJ (.obj) format. I hear Amira can export in that format.
If it's actually a volume data set, my guess is you just want a file
that is everything after that "@1". Then you can manually instruct
ImageVis3D what the volume sizes, etc. are and load the file that way.
Unfortunately I do not think we support loading only a mesh into
ImageVis3D at present -- it has to be associated with some volume data.
This should arguably be changed. In the meantime, just create a 1x1x1
"volume" and load it into ImageVis3D, then use 'File | Add Geometry to
this Data Set' to import your OBJ-format mesh.
Cheers,
