1. Driving a virtual submarine Driving a virtual submarine through an active hydrothermal vent site on the ocean floor: Exploring NOAA seafloor data over the Internet - NGI/NW/04 Bob Embley, PMEL HPCC Project Review Meeting, Norman, Oklahoma, 24-25 May 2000

2. There have been some unfortunate but unavoidable delays Funds arrived 3 months later than we expected The lead developer (at Stanford) changed jobs It took a long time to complete the PMEL/Stanford contract Then the contractor had difficulties in hiring staff Therefore, the project is behind schedule However, now that the project is underway, progress has been excellent. Status Driving a virtual submarine

3. Milestones Driving a virtual submarine

4. Quick time movie… Alvin submarine “flying” around a 3D hydrothermal vent on the sea floor fly-through of a 3-D terrain that is based on a real hydrothermal vent site on the East Pacific Rise. The terrain is from high-resolution bathymetry, then it is draped with a "texture map" that is based on video and photographs for the bottom, and finally additional 3-D objects like black smoker chimneys and tube worms are added in. This 3-D environment is then used as the basis of an interactive program that lets users move from site to site as if they were in the Alvin submersible. There are hot-links embedded in the environment which link to real video and photographs of specific features of interest. This project is focused on a different area: the NeMO Observatory and the recent eruption at Axial Volcano on the Juan de Fuca Ridge http://newport.pmel.noaa.gov/~chadwick/alvinSnd3.mov Quick time virtual reality (QTVR) of a sea floor scene near a vent… Zoom in and out, turn through 360 degrees http://www.geol.ucsb.edu/~weiland/epr_qtvr.html Example results Driving a virtual submarine
