I think the X3D/VRML Background node is not a spherical rendering. It 
is a box with six sides.

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)
