Linus,

You left out the "application" type. Does it make any
sense to put 3D geometry in this classification?

In the meantime, is your suggestion that "VRML" should
be in the "video" MIME type? What is your opinion
concerning the introduction of a new MIME type
called "product/object model data" which would cover
3D geometry models such as IGES, VRML, PHIGS, and STEP.

Philosophically speaking, things have already broken down.
If you have image, you've got video capability. So why was
this distinction made? And since VRML, like DOOM, consists
of "moving" images, why don't we call it "video"? :-)

I am aware of patented & proprietary techniques that
enable binoccular vision on ordinary displays (i.e.
give you illusion of stereo viewing & depth, but require
no specialized hardware to acheive the effect).

So, really, you DON'T need this type.

> video3D: moving 3D image capability

And, since moving images are "just" a sequence of stills,
this is redundant as well.

So the real question is, why did the IETF think that video is,
in some "fundamental" way, different than image? Can we use
exact same arguments for 3D? After all, video has a LOT more
in common with "images" than 3D ever will.

More stupid philosophy from linas ... apologies in advance.
