Web 3D Applications
Each one of MBARI's ROV dives is available in a virtual world replay
via the Institute's Expedition
database (internal access only). Video frame grab images are placed
along the dive track for easy visualization and comparison with geologic
structures as shown in high resolution renderings of the terrain. The
3D Replay system has been implemented with open specifications and software,
namely GeoVRML. See presentation links at bottom of this page for the
Two transect dives on the Cleft segment of the Juan
de Fuca Ridge.

these dives (230 MB AVI file) with narration by Mike McCann and Debra

(The video has an audio track, you may have to turn your speakers
up a bit it to hear it.) The purpose of this online video clip is
to demonstrate the web access to these visualizations and how you
would use the interface to interact and view the data. The visual
quality is low as a result of the encoding.

These visualizations use have been successfully
tested on SGI Irix with Netscape 4.5, Windows 95/98/NT with IE 4,
Netscape 4.7, and Netscape 6, Power Macintosh and iMac with Netscape
4.7 (follow installation instructions carefully). The trickiest part
is getting the plugin installed properly, after that is done you can
explore these worlds as well as many other 3D worlds that are on the
