X3D to VRML conversion
Hi Dr. Meng, Thank you for your informative reply. That was very helpful. I was wondering if I could ask another quick question. I don't think that in Chimera, using the VRML format one can save non-surface information, like the backbone structure of a peptide (but one can display it). So I saved the information in X3D. And now, I'm trying to convert back to VRML format to be able to display it. I got completely lost when looking for some software to do this conversion. I tried using something called X3D to VRML97, but got a "segmentation fault" when I tried to open up the created VRML file. Has anyone faced this sort of an issue ? Thanks a lot, Nihshanka
Hi Nihshanka, Many others have mentioned the difficulty converting X3D to VRML. Janet Iwasa at UCSF has had some success using the X3dToVrml97.xslt conversion program, but says it is very slow and runs out of memory for large systems. I'll send you her email address in a separate email if you would like to ask her questions. In Chimera version 1.2255 the "File/Export Scene"menu entry allows directly exporting surfaces as VRML, but does not export molecule models (ribbons, ball+stick). Greg Couch in our lab has improved that code to also export molecular models, but we have not yet distributed a version of Chimera with that capability. I just tested it and find that it correctly exports molecules in ball and stick style and sphere style, but ribbons were not exported correctly (the VRML only showed a little piece). Hopefully the working version will be available in the next Chimera snapshot (within a few weeks or months). Greg is at a conference, and could give a better estimate of when it will be available when he returns later this week. Tom
