Janet Iwasa reports problems exporting ribbons and nucleotide renderings as x3d, problems converting x3d to vrml, and problems with POV and Renderman output.

Hi Tom, Unfortunately, I still ran into a bunch of problems. The structure I had was a bunch of ribbons with some colored sphere residues. When I exported the scene as x3d and used the vrml converter (which did work but took forever on my home computer) it only appeared to export the sphere surfaces, not the ribbon. I ended up using a different program (called 'ribbons' - I think I talked to you about it before) to make a vrml of the ribbon structure. Then I took the colored spheres and superimposed it over the ribbon in Maya. It was pretty time consuming, but worked in the end. The structure (which was a nucleosome) also had some nice DNA representations using the depiction > nucleotide option, and those didn't seem to get exported to x3d either (could have been a problem with the x3d -> vrml conversion -- hard for me to tell where things went wrong). So I used multiscale models and exported the DNA as VRML that way, which worked perfectly, as always. I haven't tested it to see whether the x3d export only works with spheres or what. It took the better part of an hour to convert from x3d to vrml (and this for only 20 or so residues!), so I would love to find a better solution... Ideas? I think I'm pretty much done with that project for the time being, but it would be really nice to have the scene export stuff working. Any clue about what's up with the pov and renderman formats? Those may be easier to find converters for. thanks! Hope you're doing well, Janet ------- End of forwarded message -------
