3-Dimensional Enhancements for Visualizing Lane Navigation Performance

Abstract : Research results are typically reported using 2-dimensional (2D) methods that include tables, figures, and charts. With the availability of 3-dimensional (3D) visualization applications, based on the Virtual Reality Modeling Language (VRML) and Extensible 3D (X3D) graphics, the Naval Research Laboratory (NRL) has employed alternative methods of information presentation. These 3D applications are displayed with viewer software on conventional Internet web-browsers and may be effectively used in oral presentations and for separate viewing on the Internet. This paper describes 3D applications that were developed to visualize Marine Corps Amphibious Assault Vehicle (AAV) navigation performances during field demonstrations and augment the 2D performance data. They depict steering patterns used to avoid surface waves, how well the drivers negotiate lane turning points, and a vehicle's vulnerability to mines and other dangers (e.g., subsurface rocks) when steered outside the cleared navigation lanes.
