I'm interested lately in Stellarium and the functionalities which it provides especially scripting. I want to make a simulation that shows the celestial sphere with some planets like Venus, Mars, and the Pole-star.
I would make a kind of animation that starts from a departure point (France) and arrives in (Canada), but in this animation, I couldn't figure out how to synchronise between time and position (Supposing that I'm travelling to Canada at a fixed speed like in a vessel).
I've already looked for some examples in the scripts folder and I read the documentation and I found that I can use
setObserverLocation() and maybe
setDate() but I don't know to synchronise between both of them to make the animation realistic.
