Welcome to VRML:
The Virtual Reality Modeling Language

Where to find information about VRML and its Viewers? Here are several sites you may want to visit:

1. VRML Archives at Web3D
   It contains many useful resouces related to VRML 2.0 (or VRML 97).

2. NIST: Cosmo Player VRML Plugin
   It is the best site to find how to install Cosmo Player VRML Plugin for major browsers. The installation programs work with any version of Windows including 8, 7, Vista, and XP.

   Recently (in Aug, 2003), I have followed its instructions step by step on how to install Cosmo Player on my Google Chrome.

3. NIST: VRML Plugin Detector
   Before or after the plugin has been installed, you might want to use the Detector to detect if your browser has the plug-in installed.

   Note: The web browser should be restarted before trying to detect a newly installed plugin.

   After my installation, I restarted my Chrome, opened the detector page and I can see the plug-in is succussfully installed:

   

Coded in 1999-2002; Based on The Bible of VRML: VRML 2.0: sourcebook by A. L. Ames et al

Cosmology: Black Hole, Wormhole and Multierse (Physics/Gravitation) According to Eistein's general relativity, a gravitational filed is just a curved 4D space-time caused by the existing matter. A black hole is a very dense object with such a deep twisted space that is looks like a funnel in a 3D space-time. Two black holes may form a Wormhole. I always wonder what if the two black holes belong to different Universes (a naive thought of Multiverse)? Here are two static models for you to play with In our animated model of the Oscillatory Universe, there is a standing wave, whose wave length is increasing (red-shift) when the Universe is expanding, decreasing (blue-shift) if the Universe is collapsing. Because we do see the red-shift, our Universe currently is expanding. Note thst the size of black holes (and galaxies) does not change with the universe. Because this model assumes our unverse is closed and periodically expands and shrinks, it is different from the Cyclic Model. The Oscillatory Universe seems to be invalidated, because recent data show that our universe will keep expanding to a deadly cold end (Big Freeze), although scientists are still looking for the source of dark matter and dark energy...
