HI,
I think the X3D/VRML Background node is not a spherical rendering. It is a box with six sides.
Best Regards,
Joe

Yeah, the IVRPA has been doing discovery for the past year or so. Now, they're ready to move forward. Folks should definitely read up on it and see if they can find any supporting info.

BTW, in terms of expanding X3D, the IVRPA would be a good organization to network with. They have an interest in seeing the growth of interactive environments and they're very professional in their approach to expanding the art. (I'm a QTVR photographer, and have been a member of IVRPA for a couple years)
