EXTENDED ABSTRACT

The Software

Visualization technology, a key component of modern geoscience research, continues to advance and evolve, enabling geoscientists to understand better complex, multidimensional geological processes. A significant barrier remains, however, when scientists using this technology attempt to convey research findings to the scientific community and to the general public, both of whom may not have access to the software, hardware, or Previous HitdataNext Hit underlying the research. We have responded to this problem by developing a unique software product for exploring 3D Previous HitdataNext Hit. Built using Trolltech's Qt and SIM's Coin3D toolkits, the software is a full-featured, cross-platform tool for visualizing geoscience Previous HitdataNext Hit. We have developed numerous versions of the software, each version bundled with Previous HitdataNext Hit and contextual information addressing a particular research interest: “ Pattern Analyses of Dune-Previous HitFieldNext Hit Parameters,” for Previous HitexampleNext Hit, or “Debris Flow Processes and Deposits in a Tectonically Active Margin Basin.” To peruse a completed project, scientists or the public need only visit our website and download a self-extracting .zip file that contains both the viewing software and Previous HitdataNext Hit. No additional software or plug-in is needed. After launching the software, users will find a comprehensive 3D project with numerous scenes organized by theme. A full suite of graphical user interface (GUI) tools, pop-up information panels, fly-throughs, and audible narration are provided to enhance the user's understanding of the geological concepts and Previous HitdataNext Hit presented in the project. Stereographic viewing is supported, along with other features found in traditional geoscience software applications.

A Rapid Application Development Process

Because each project is unique with respect to the Previous HitdataNext Hit, GUI elements, and other features found therein, the source code from one project to the next is likewise unique and would typically take a considerable amount of time to write for each individual project. We avoid this time sink through the use of a rapid application development process developed in-house. Using this technique, a detailed spreadsheet for each project is created; this spreadsheet contains information about the geological Previous HitdataNext Hit, GUI elements, and other features to be included in the final project. When the spreadsheet is complete, it is converted to C++ source code using software written in-house. This code is then compiled into a project executable, which is then ready to be shared with the scientific community and public.

Previous HitExampleNext Hit

All of our projects begin with an “Introduction” page that includes acknowledgments and a brief tutorial for exploring the project. Arrayed across the bottom of the main project window are buttons which the user can click to view different scenes in the project. For the aforementioned “Debris Flow Processes” and “Deposits” project these include: “Introduction,” “Region,” “Study Area,” “Morphology,” “Formation,” “ Dropcore,” and “Structure.” Clicking one of these “scene selection” buttons has the following effect:

  • the 3D Previous HitdataNext Hit window is populated with Previous HitdataNext Hit specific to the chosen scene, and
  • various GUI elements—buttons, sliders, etc—associated with the scene are now visible.

If the user clicks “Region,” for Previous HitexampleNext Hit, regional Previous HitdataNext Hit populates the 3D Previous HitdataNext Hit window. Datasets include: lines denoting survey blocks, faults, and channels; a 3D surface representing regional topography and bathymetry; and points indicating well and dropcore locations. These and other Previous HitdataNext Hit layers can be turned on or off with the click of a button. The user can also select which image should be overlaid on the topographic surface; an image depicting elevation is the default, but others derived from satellite imagery or aerial photography are also available. Similarly, users can select which attribute Previous HitfieldNext Hit of a point Previous HitdataNext Hit layer should be used to color the points in that particular layer; for Previous HitexampleNext Hit, we can choose to visualize the percent sand, silt, or clay of individual dropcore depending on which attribute we elect to feature. To help explain the Previous HitdataNext Hit and geologic concepts presented in a particular scene, panels with text information and/or images pop-up by moving the mouse over select buttons or features within the 3D scene. Viewpoint buttons enable the user to change the viewpoint to pre-defined locations; of course, the user can also rotate, translate, and zoom in to or out of the scene using the standard click-and-drag sequence employed by most 3D viewing applications. As with most scenes, a slider is present in “Region” with which the user can adjust the vertical exaggeration of the 3D Previous HitdataNext Hit.

To close the “Region” scene and open another, the user simply clicks one of the other scene selection buttons. Some scenes have links to higher resolution sub-scenes. In the “Morphology” scene, for Previous HitexampleNext Hit, the user can click on one of four hot-spots within the scene; doing so brings up very detailed Previous HitdataNext Hit of the selected area including horizons extracted from seismic Previous HitdataNext Hit and 3D fence diagrams. Fly-through animations in which Previous HitdataNext Hit and information panels turn on and off at set intervals enhance user understanding of the Previous HitdataTop and concepts presented in this and other scenes throughout the project.

Summary

Our custom software enables us to share research findings in a unique, interactive 3D viewing application. A rapid application development process created in-house ensures that the turnaround time from project conception to completion is kept to a minimum. Screen captures from existing projects and a sample, completed 3D project can be downloaded at http://www.beg.utexas.edu/coastal/gcags2008/3d.htm.
