Hi Selden,
Ummmmm, no, it doesn't, because you and Chris already explained these things, thank you <smile>.
Chris's earlier message stated, "Each of Celestia's modes--follow, sync orbit, lock, chase, and free [universal]--together with one or two objects defines a coordinate system". And I now know that the user can set the Coordinate System by pressing a key in the user interface (Chase, Lock, Follow, Sync Orbit, or Universal), or by using the setframe script command. But, there is no "observer" coordinate system keystroke that I've seen, even though this coordsys can be set via the setframe script command.
In another topic, Chris wrote, "The coordinate system names accepted by setframe map to Celestia's modes as follows:
equatorial - follow
geographic - synchronous
lock - lock
chase - chase
universal - no mode selected (e.g. you just pressed ESC)"
However, "equatorial" is not one of the setframe Coordinate System options, and he didn't list "observer". Thus my follow-up questions.
In my last message, I asked: "Care to take a crack at filling in the missing Celestia "modes" to the setframe CoordSys values I listed?", which was referring to the following:
Code: Select all
CoordSys Celestia Mode / Astronomical Term
-------------- ---------------------------------------------------
chase ........ Chase -- any astronomical term for this?
ecliptical ... Follow?
geographic ... Sync Orbit
lock ......... Lock -- any astronomical term for this?
observer ..... Celestia mode? -- any astronomical term for this?
universal .... None -- no mode selected
The four questions this list puts forth are as follows:
1) Is there an Astronomical term for Celestia's "Chase" mode?
2) What Coordinate System does Celestia's "Follow" relate to?
3) Is there an Astronomical term for Celestia's "Lock" mode?
4) What Celestia mode does "Observer" relate to? Since this is a Coordinate System that can be selected by a script writer, what is the corresponding keystroke in the user interface?
I hope this explains my questions more clearly.
