Chimera can export map surfaces in several 3-D file formats Wavefront
OBJ, POV-Ray, RenderMan, VRML, or X3D using menu entry File / Export
Scene.... The format for objects embedded in 3D PDF is called U3D which
Chimera does not export. I used a program called MeshLab to read OBJ
format produced by Chimera and write U3D format, then used another
program to convert LaTeX to PDF (pdflatex). Here's an example showing
EMDB map 1356. It requires Adobe Acrobat Reader 8.0. It will not
display on Mac OS 10.4 Preview.
Producing the file was painful and Chimera can't export the surface
coloring in OBJ format. I think it would be more interesting for the EM
Databank to show 3D models in the web browser like JMol shows PDB
models. I don't know if a java applet has been written to do that.
Perhaps JMol could do it.
