| dc.description.abstract | The next generation of Models and Simulation (M&S) for use in determining future force design, developing doctrine, training military leaders, and performing acquisition for the Army After Next is currently under development. The Army M&S program is developing software called One-Semi Automated Force (OneSAF) to fulfill the objectives of M&S. Special Forces units train for terrorist scenarios such as capture and occupation of structures that may include innocent hostages. Given available information about the building at the time, a realistic simulation is desired in order to train to neutralize the threat. At present, OneSAF has a capability to perform military operations within buildings, but a rapid method to produce a building model for the synthetic environment does not exist. In September 1999, ITL began an investigation of the visualization of buildings in the OneSAF environment. This report details the findings of this preliminary study. | en_US |
