I'm not seeing much info on the use of using VRML or X3D on my usual blog circuit... so I thought I would do a quick post on the topic to point interested people in the right direction.
Setting up your web browser to view 3D files:
VRML Plugin and Browser Detector
Cosmo Player (View VRML Files in a web browser...I am currently using this to quickly test models)
After you have installed a web browser plug-in, you should be able to freely view 3D files...
Here are some other helpful resources....
X3D for Developers
Give it a go... it's a lot of fun!
