Abstract:

13. ABStRACT Maximum 200 words The objective of this Phase II SBIR project was to provide the U.S. Army Topographic Engineering Center TEC with a Three-Dimensional 3-D Modeling Station composed of hardware, software, and development tools, and to create and populate a data base with models of suitable features found in Defense Mapping Agencys Interim Terrain Data ITD set, at an appropriate level of detail. A low-end DOS-based system and a high-end UNiX-based system were configured to meet the varied requirements of simulator data base development, and over 160 3-D feature models were created using the modeling stations. These models represent terrain features, both natural and man-made, defined in the DMAs lTD. Models are available in AutoCAD DXF, IRIS Open Inventor IV, and Wavefront OBJ formats. A relational data base was designed and created to store the model information, and serves as a standard model library. A DBMS system with the X-WindowMotif graphical user interface was developed to provide tools for model data manipulation and management. Dynamic model placement tools were developed for placing models into simulation scenes. Using these tools, the following three feature types can be placed point, linear, and area.
