Hey Tom,
Were you using the chimera VRML viewer when you tested the new x3d2vrml output? I had the same exact problem in my testing of the code before submitting it, and Conrad told me that the Chimera vrml viewer is less than perfect when it comes to complex geometry (surfaces and ribbons). I don't know if you were using Chimera, or even if it is the only problem, but when I tested the code using a third party viewer, ribbons and surfaces worked fine!

Hi Ben, Yeah, I tested Chimera VRML output by reading it back into Chimera. I agree that the fact that ribbons did not display properly could very well be a problem with the Chimera VRML renderer rather than the output. I just displayed a Chimera round ribbon (1a0m) using FreeWRL 1.15 on Linux and it displayed correctly. It gave about 30 warnings like the following which may or may not be important: WARNING -- node Normal may not be ok as a field of type normal (...called from VRML::Field::SFNode, 1363) It sounds like you are the one who have worked on the Chimera VRML output rather than Greg. Thanks for working on this. I think it will be useful to many people. Tom
