3. DON History • Late 2004, CE&R Workshop, DC Area • The NASA Simulation Based Acquisition (SBA) team hosted a workshop for the CE&R contractors. The purpose was to discuss SBA, NASA’s intended role for SBA, and to solicit feedback from the CE&R contractors as to the best way to meet NASA’s goals in this area. • Workshop led by Don Monell. One of the items presented included a new focus area called “Visualization and Animation Distribution (V&AD)”. Mike Conroy was introduced as the lead for that area. That brings us to today. • Local SBA and IM&S Workshops • Team met with several centers (KSC, JSC, LaRC, MSFC, ARC) to talk SBA. One of the side items for each of these discussions was V&AD. • Through these sessions, a picture began to emerge as to what people were looking for in terms of V&AD type services. More importantly, as these sessions progressed, other modeling and simulation related challenges began to emerge. • These non-V&AD challenges, began to resemble V&AD like challenges. • They were not prime requirements, but were more nice to have kind of things. • There were a lot of them, and every Mission Segment Simulator had them.

4. Common Threads • The ability to re-play a simulation at some later date, any date • The ability to stop a simulation, back up, and look at something again (TIVO) • The ability to post-process a simulation, make it look prettier, pull out only the parts you need to present • The ability to have multiple people look at the simulation, at the same time, in different places, followed by the desire to add multiple times in multiple places • The ability to use simple hardware to view the simulations, as opposed to really expensive stuff • There is nowhere near enough money in this element to do any of this This Led To….

5. DON Design Goals (January, 2005) • Ubiquitous Access to Simulation Results • Real Time on High and Low End Systems, Later on Both • Does not require entire team synchronized in time • Simulation Recording Service • Recreate Results, Validate Changes, What Were We Thinking • Orders of magnitude improvement over video file, DVD or VHS • Post Processing of Simulation Results • Comparison of Results, High Order Products, Detailed Analysis • Tell how was this different from that, you want it from THAT viewpoint too? • Work with Today’s Tools Now • TRICK, NEVA, SEE, DES • Wide spectrum to define interfaces, touch as much of lifecycle as possible

6. Important Words • Scope • The DON scope is limited to displaying and distributing information. DON does not perform analysis, it reflects the results of authoritative analysis for others to see and operate upon. • Authoritative Analysis Tool • Any Tool, most typically an IM&S Mission Segment Simulator, that is used to perform analysis. This tool will have been accredited by whatever process IM&S deems in necessary to authorize use of the tool for IM&S work. • State • For the next day or so, the word “state” will refer to the attributes associated with an element that is displayed as a part of a simulation. The attributes of interest are the same attributes that are of interest to the rendering engine in a computer graphics program. These include: what element is to be drawn, where it is to be drawn, when it is to be drawn and which way is it turned. • Model • The model is the 3-D geometric representation of the item to be shown. It does not include things like the mass of the item or what it is made of. Those items are of interest to the authoritative tool, not to DON.

7. Video Products • DVD • MPEG,Q-time DON Architecture Model Live State Data Path Live Model Data Path Post Sim Path transparent • ICE • Model Source • Archive for everything Authoritative Analysis Tools • Data Editor/Viewer: • Pull states and models from ICE • Edit, Annotation, Combine • Check new results back into ICE • Make Movies Distribution Engine • DON Sim. Dist. Process • Tools get data from ICE, do tool stuff • Tools send state info to ICE and/or Dist Eng • Dist Eng gets models from ICE • Dist Eng gets State from Tools or ICE • Dist Eng sends State and Models to Viewers • Dist Eng records State information • Dist Eng sends State info to ICE afterwards Simulation Viewer (viewpoint control, conferencing) Analysts
