GLOBAL SCENES

Global Petrological Database of the Ocean Floor (PetDB) scene
Visualization of the locations of geochemical and petrological sample-based data stored in the PetDB database (http://www.petdb.org/), juxtaposed on a topography map of the world. Data sets include: abyssal_hill, aseismic_ridge, failed_rift, forearc, fossil_ridge, fracture_zone, incipient_rift, ocean_island, oceanic_crust, oceanic_plateau, off_axis_spred_center, psread_center, seamount, trench, and triple_junkction.

GUIDE TO USING VISUALIZATIONS

All visualizations are IVS Fledermaus "scene" files consisting of visual objects, or ".sd files".
Download the free scene viewer, iView3D, from the IVS 3D website (http://www.ivs3d.com). This program works on Mac OS X, Windows, and Linux.
Start iView3D and choose "File > Open Scene File..." to select scene file.
Depending on the size of the scene file and the specifications of your computer, opening a scene file may take between a few seconds to a minute.
We recommend using a 3 button mouse to navigate through the scene file. There are three basic interactions :
- ROTATION : Click the left mouse button and drag left or right to rotate about the vertical axis. Click the left mouse button and drag up or down to rotate about the horizontal axis. The turntable widgets (seen in the center of the screen) can also be used for rotation if you click and drag on the widget.
- TRANSLATION : Click the middle or right button at the location in the scene you wish to examine, this will re-center the view at this point.
- ZOOM IN & OUT : With the middle button held down, drag up to zoom in or drag out to zoom out.
The 'Camera > Reset Camera' menu option is used to return the view to its initial starting position.
Individual objects of the scene (.sd files) can be turned on and off by clicking on "View" in the menu bar.
