QUAKEWATCH PROJECT - SHORTCONTENT
A VIRTUAL RECONSTRUCTION OF THE FIRST KNOWN INSTRUMENT FOR INDICATING EARTH MOVEMENTS AND JUDGING THEIR DIRECTIONS, INVENTED BY CHANG HENG IN 132 A.D.THE EXISTENCE OF THE INSTRUMENT IS DOCUMENTED IN THE "HUO HAN SHU" (HISTORY OF THE LATE HAN DYNASTY); THE INSTRUMENT ITSELF IS LOST.
One thing about this project was, to give Chang Heng´s seismograph again a shape, the other thing was to implement it´s original function: Indicating earthquakes and judge their directions.
So, that for a CGI script is catching near-realtime-earthquake-data from the United States Geological Survey, Geologic Division - USGS, in the internet, from their earthquake information pages. After that, if relevant data (not older than 15 minutes) is recieved, a script within the vrml-file is triggering ´quake-action´ on the model....
Screenshots of a flight through the vrml-model:
