During the live coverage of the LDEF retrieval by the shuttle, TV showed what seemed to be an animation of the retrieval process as it was happening, ie. it would seem that the data being relayed by the shuttle (its position, LDEF's position and the robotic arm's position and velocity) was being animated in real time. This is not the sequence where one sees a 3D view of the shuttle and satellite, but it was a screen with 3 views of the shuttle, satellite, and arm. Also, the pictures seemed to come from a control center. To me, the computer seemed to be a Silicon Graphics. Can anybody confirm that? -- pff@beach.cis.ufl.edu - Pablo Fernicola - Machine Intelligence Laboratory - UF IF YOU CARE ENOUGH TO READ SIGNATURES ...

Can anybody confirm >that? What you saw was at Johnson Space Center, and I cannot comment on what they have or don't have. However, here at Goddard Space Flight Center, we have something that is very similar called 3D-Monitor (3DMon). 3DMon was initially developed on an IRIS 2400, but the first release actually used during a mission was on a 4D/60. I was one of the team that helped develop the first two versions. It has a similar display to what I saw on network TV, but we do not have a data display window up on the IRIS, it is on a vt100 type terminal. Our fourth window is what ever view was on the screen when it was put into quarter screen mode. The views can be specified in a large number of coordinate systems (shuttle, payload, end effector, elbow, GCI (GeoCentric Inertial), etc.). The user is also able to modify any view by changing the angle of view, the point looked at, the eye point, and twist through either via the dials or through menu picks. If you want further information, contact me sometime after the 22nd, as I am going away on a business trip.
