Objectsim - A Reusable Object Oriented Dis Visual Simulation, Mark I. Snyder
Objectsim - A Reusable Object Oriented Dis Visual Simulation, Mark I. Snyder
Theses and Dissertations
This research designed and implemented a reusable Distributed Interactive Simulation DIS visual simulation architecture for Silicon Graphics platforms. The goal was to research software architecture technologies and to create a design and implementation using these ideas. The architecture was designed using object oriented techniques to provide the ability to customize it via inheritance extension. The resulting design was implemented using C and applied to several DIS visual simulation projects in the Graphics Lab at AFIT. The architecture, named ObjectSim, was successful in its goal of providing a reusable core for the DIS visual simulation projects in the Graphics Lab at …
Graphical Tools For Situational Awareness Assistance For Large Battle Spaces, Brian B. Soltz
Graphical Tools For Situational Awareness Assistance For Large Battle Spaces, Brian B. Soltz
Theses and Dissertations
As virtual environments grow in complexity and size, users are increasingly challenged in assessing situations in large-scale virtual environment. This occurs because of the difficulty in determining where to focus attention and assimilating and assessing the information as it floods in. One technique for providing this type of assistance is to provide the user with a first-person, immersive, synthetic environment observation post, that permits unobtrusive observation of the environment without interfering with the activity in the environment. However, for large, complex synthetic environments, this type of support is not sufficient because the portrayal of raw, unanalyzed data in the virtual …
Rendering The Out-The-Window View For The Afit Virtual Cockpit, W. Dean Mccarty
Rendering The Out-The-Window View For The Afit Virtual Cockpit, W. Dean Mccarty
Theses and Dissertations
The Air Force Institute of Technology (AFIT) is developing a distributed interactive flight simulator, the Virtual Cockpit, using commercial graphics workstations and helmet mounted displays. The Virtual Cockpit communicates with other simulators via local and long-haul networks using the SIMNET protocol. The work reported in this thesis focuses on developing the terrain database for the synthetic environment and on rendering the pilot's view of the database. There are many different file formats for describing 3- dimensional geometric polygonal objects. An analysis of three formats, AFIT GEOM, the Naval Postgraduate School (NPS) DRP, and Software Systems' Flight, is presented. Each file …
