[3dem] PDF with 3D models

[Bernard Heymann]

I see Adobe Acrobat 3D ($699) can be used to create 3D PDF files.  
Chimera can export VRML scene files that can potentially be imported  
in Acrobat 3D, so that might be a way to convert map representations.  
However, I would think that the files will be big (VRML files of map  
isosurfaces are typically tens of megabytes).
