Viewers for DRAWxtl
Information about VRML is available at The VRML Repository. Viewers and browsers may be obtained through the links available there. My personal choice for a VRML97 viewer is Cortona VRML Client, which is a plugin for Firefox, Mozilla, Internet Explorer and Netscape browsers. This plugin only runs under Windows or Mac. For VRML 1.0 compatibility, you will also need the VRML 1.0 Converter. Other platform-independent, freeware viewers for VRML97 can be found at http://openvrml.sourceforge.net and http://www.crc.ca/FreeWRL.
The source of information about POV renderers and other documentation is through The Persistence Of Vision-Raytracer official home page.
