> IGES is a commonly used format for CAD model (3-D or 2-D) interchange.
An alternative is to make it part of a new content (Media?) type, as
opposed to a subtype of "application". IGES serves many applications.
We are working toward proposing "world" as part of the VRML effort.
VRML is a 3D extension to the Web. Check out http://vrml.wired.com/
The prototypes are proceding with x-world/x-vrml (and the less polite
using simply world/vrml)
I strongly believe that the 3D model is a fundemental datatype. IGES is
one, DXF, CGM (with 3D extensions), dof, off, iff, iv as well as
application specific files.
