Hi Tom
Does CHIMERA have the ability to export a map format which can be used by 3D PDF?
We would like to make the EMDB maps available in this format.
All the best Richard
Hi Richard, 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. http://www.cgl.ucsf.edu/home/goddard/temp/emd_1356.pdf 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. Tom
