So of course both of these are slight simplifications, but what is the connection between the two? If the earth is basically a circle, is an ellipse just a parabola stretched around a circle? Is a parabola just an approximation of a tiny part of an ellipse? How high do you have to be before you change your calculations of a trajectory?

The Math ain't mathing.

They move in ellipses on earth as well, but it's cut short by hitting the ground. Also, air resistance affects the trajectory so that anything thrown/shot will eventually return.

KSP is such a great game. Such a shame what happened to KSP2 but that was doomed from the start.

[–] [email protected] 1 points 1 day ago* (last edited 1 day ago) (1 children)

Yeah, KSP2 was botched on so many levels, primarily by Take2.

Looking forward to seeing what comes out of KSA, though. With many of the old devs and modders of KSP1 on board it looks like they have a good start.

I just hope the used a 64-bit engine this time

[–] [email protected] 1 points 8 hours ago (1 children)

What are you talking about? KSP 1 has been 64 bits since forever, or was that only on Linux?

[–] [email protected] 1 points 2 hours ago

The engine internals were 32 bit, limiting the size of the solar system due to 32 bit floating point rounding errors when you get too far from the center

[–] [email protected] 1 points 1 day ago* (last edited 1 day ago) (1 children)

They're very much 64bit, as they're avoiding unity all together. The standard framework of actors and scenes don't really work for a game at that scale, so they decided to roll their own, and they're calling it the Brutal Framework "because it's quite brutal to work with".

So far the result is really impressive looking, and since there aren't many layers of abstraction to work via, the performance is pretty impressive too.
