This is an area I use to test and demonstrate various aspects of VRML
as a means of distributing 3D models and systems to end users.
Some of the samples here are intentionally designed to push the graphical
processing power to the limit, initially I suggest you choose a large value
of subsampling. Most "good" cards can handle the large datasets
but some of the examples may take some time to transfer
aver the data on a slow connection.
I haven't tried these on machine without OpenGL (or DirectX) hardware
support, the 3D interaction will certainly perform rather poorly in those
For those cases where the mime type is required, it is
model/vrml. In the old days it was common to use
"x-world/x-vrml" and that may still be required for some sites with VRML files
but it won't work here.
