variation of Obliquity with a celx script

[Vincent]

Hi,

I would like my pupils to use Celestia to find that the difference between the the day and night lengh comes from the inclination of the rotation axis. For that, they'll have to make this inclination change by pressing a key.


Is it possible to do that with a celx script ? I mean modify the obliquity value of the earth by pressing a key ?

Thanks a lot !

I just realised that's not possible because Celestia would have to be reloaded...

Maybe I could do that by adding other earth definitions with different obliquity values and give each definition a time limit with the beginning / end commands... Then, I could make a celx script to change the date by pressing a key, each date corresponding to an obliquity value...

Thanks for the help
