I want to be the first to open a virtual bar. Coming soon to a site near you.
Serious. I'm going to do it. I was looking for a test scene.

OK. I will go with the agreed convention. I will also adjust my modeller
so that it essets up to be Y if VRML is the default target.

Does the 1.1 spec clarify this issue? Something like: "By convention, Y
is the up direction. This makes it easier to link worlds together." That
is different to saying that Y is the default. Defaults are, after all,
there to be changed. ;-)

By the way, this doesn't mean that I am happy about browsers that scesw up
if my world and my world only has Z as up. Lets get into real 3d folks.

Cheers,
Steve.
