 Jmol (11.8) can export to the '''''Intermediate Data Text Format''''', a human-readable format that can be transformed into the binary [[#U3D|U3D]] format and hence be later [[File_formats/3D_PDF|inserted into pdf files]].
 Some potential future improvements:

 * Embed the Jmol state script in the U3D file, so one can load the pdf file itself (<code>script "filename.pdf"</code>) or the U3D file itself (<code>script "filename.u3d"</code>) back into Jmol.
 * Embed a CML source file in the script too, and we would be a step further down semantic publishing.

 Two files will be generated: {{file|obj}} and {{file|mtl}} with the same filename, which includes the needed ''materials'' information.
