VRML (Virtual Reality Modeling/Markup Language) Question:

There are now several browsers available for Macintoshes, and not just for PowerMacs either. Browsers for 68K Macs include ExpressVR, a Netscape plug-in, and Virtus Voyager, a stand-alone VRML viewer or helper application.

Netscape's Live3D for PowerMac is gradually becoming stable. Other PowerMac software includes ExpressVR, Voyager, Whurlwind, and Equinox.

All of the previous are VRML 1.0 browsers. The new kid on the block is RealSpace, with yes, a VRML 2.0 browser for PowerMacs.
