A10 DIS Demo Self running demo of a DIS scenario in which two A-10 attack aircraft are attempting to destroy 7 ground targets near an airfield. |
INTERACTING WITH THE DEMO While the default is for the demo to operate in a hands-off fashion - automatically moving the eyepoint to follow the action, you can also interact with both the Stealth and Logger in a variety of ways. LOGGER CONTROLS Playback of the Logger recording can be paused or stopped and restarted using the buttons on the XLogger GUI. In addition, the speed and direction of playback of the recording can be manipulated with the Time Scale slider. Use the fast forward and rewind buttons to jump to the end or beginning of the recording. BASIC STEALTH CONTROLS To gain control of the eyepoint, click on the Stealth Options button on the Stealth GUI. Then, from the ViewControl Options menu in the Stealth Options window, select Ignore. The Stealth will now ignore the eyepoint scripting commands it receives from the Logger. (To restore eyepoint control to the Logger recording, reselect Process All from the ViewControl Options menu.) Click on the Stealth Control button on the Stealth GUI to bring up the Stealth Control window. Here, you can switch among the Stealth's many View Modes. In absolute mode, the manual controls (arrows) control the position of the eyepoint. In the other modes, the eyepoint is slaved to the position and/or orientation of one or more vehicles, and the manual controls determine the position and/or rotational offsets from the tethered vehicles' position(s). ADVANCED STEALTH CONTROLS The keyboard or a Spaceball(TM) may be used instead of the GUI to control the eyepoint. The arrows on the keyboard numeric keypad correspond to the GUI's translation arrows, with the 9 and 3 keys controlling altitude, and the 7 and 1 keys controlling the distance moved in response to the translational keys. The arrows arranged in an inverted 'T' on the keyboard correspond to the GUI's orientation controls. There are 8 presaved View States (combinations of View Mode, attached entity, and offset). To switch among them, click on one of the numbers 1-8. The List of Entities window in the Stealth GUI shows all of the vehicles in the exercise, and allows you attach to one by clicking on the entity, then clicking 'Attach' below the list. The other GUI windows should be fairly self explanatory. The full-status Heads-Up-Display may be toggled to a smaller text-only HUD with the F4 key. Performance may be slightly better with the text-only HUD. SENSOR VOLUMES The Stealth's capability to display translucent volumes to represent active electromagnetic sensors is off by default, but it may be toggled with the 'e' key. When enabled, you will see a purple volume eminating from the dish on the SA6-Radar under the camouflage canopy.
The visual database is modeled from the Holister Airport in California. At the time of recording, the A-10s were being controlled by a man-the-loop simulator flown by Carl Suttle of MultiGen Inc., using a BG Systems FlyBox(TM). The target entities were being simulated on a separate machine by a simple Computer Generated Forces application, while the Logger ran on a third machine. All of these applications communicated over ethernet using MaK's VR-Link(TM) DIS Networking Toolkit. The demo is playing back the logger file and viewing it suing Mak's Stealth product.
CREDITS Both the Stealth and Logger are commercially available products from MaK Technologies Inc, the industry leader in Distributed Interactive Simulation. Both applications are built on MaK's flagship product - the VR-Link DIS Networking toolkit. The Stealth is also built on IRIS Performer, the high-performance real-time graphics toolkit from Silicon Graphics. Moreover, the Stealth is based on Performer's perfly sample application. The Stealth runs across the entire Silicon Graphics product line. The terrain database and all vehicle models are in Flight(TM) format. They were created using MultiGen(TM), a three-dimensional graphics editor from MultiGen Inc., the industry leader in 3D graphics authoring tools.

WHAT YOU WILL SEE The recording contains a DIS scenario in which two A-10 attack aircraft are attempting to destroy 7 ground targets near an airfield. At the time of recording, the A-10s were being controlled by a man-in-the-loop simulator flown by Carl Suttle of MultiGen Inc., using a BG Systems FlyBox(TM). The target entities were being simulated on a separate machine by a simple Computer Generated Forces application, while the Logger ran on a third machine. All of these applications communicated over ethernet using MaK's VR-Link(TM) DIS Networking Toolkit. BACKGROUND Distributed Interactive Simulation (DIS) refers to the concept of interconnecting many manned and automated simulators so that real-time person-in-the-loop multi-player training exercises or gaming scenarios are possible. Each vehicle simulation might be running on a different machine, but all of them interact in the same virtual world. This is accomplished through the exchange of network packets according to the DoD's DIS Protocol. MaK's Stealth Observer is an eyepoint into a DIS virtual world. It is an interactive simulation of an invisible observer, unobtrusively observing the exercise through a 3D out-the-window view. It receives data on the position, orientation and other state of each vehicle in the virtual world from remote simulators in the exercise, and renders the scene from its current vantage point. MaK's DIS Data Logger is a VCR for a DIS exercise. It can record all information sent out on a network by simulators participating in a particular DIS exercise, and play it back later. When the recording is played back, it is indistinguishable to a network observer whether the simulators are currently running, or whether a recording is being played. This directory contains demonstration versions of MaK Technologies' Stealth and Logger applications. Both have been modified so that instead of a network being used for communication, the Logger plays directly into the Stealth. In addition, several capabilities of both applications have been disabled for this demo: The Logger's record mode has been disabled, and you will not be able to play back any files other than montyDemo.lgr. The Stealth will not look for the configuration files that are normally used to set initial parameters and indicate which terrain database and vehicle geometry models to use.
