[dev notice] Screenshots Heavy Tease Post; Alpha Centauri AB (WIP of validation, adjustments)

So the Alpha Centauri AB system is generated. I say AB, because Proxima Centauri will be its own star system in FARC; there is always debate if Proxima is part or not of ACen AB regarding of the distance of this red dwarf star vs the two other stars.
Since FARC isn’t an astrophysics program but a game, I took the decision too make it a “stand alone”, it doesn’t change much to the game anyway.

For now ACen AB is in validation and adjustments phase, ie; I must validate a correct minimal size for the asteroids, I must sort the the satellites according to distances (a limitation of my universe generator, so I must check it and sort it, even remove duplicates if any, by hand), and there are two satellites Alpha Centauri B3-1 and B3-7 that I must review and try to make a somehow believable surface map after their generations, or I will generate them again, because one them is particularly full of… life and I ejected it during the generation because I was lazy to work its surface… a mistake I know. The other one has life too but is pretty secondary.

Enough talk, it’s time to present the screenshots, just consider that a WIP outside of the surfaces that are final. I will comment for certain parts.

First alpha Centauri A:

A1, a very hot telluric planet with hotspots tectonic activity. not really a Venus because its atmosphere pressure is only 249.23 mbars but certainly a dangerous one. some winds can go as fast as the range of 100-150 m/s.
But hey the planet is pretty rich in metals and uranium ore, so what are you waiting for? haha!  Distance: 0.24 AU.


Since A2 is an asteroid, there is not much to show (I use standardized and basic 3D objects for asteroids and the surface maps are standardized too).
A3 (the outer bright circle in the first screenshot) is the asteroid belt of the system…


…and ACen A3-5 is one of the two planetoids of this belt. Yep, it looks like a Death Star in this shoot because of the biggest crater on it. The craters are generated dynamically in Fractal Terrains Pro via planetary bombardment and the results can be mixed but most of the time pretty good, especially in the 3D view.


ACen A3-6 is the second planetoid of this belt, a pretty hammered surface. As you can see, I try to generate maps that are personalized even if sometimes a bit equivalent due to the planets’ features and data.
The rest of the objects of the belt are asteroids so, again, nothing much interesting to see.


This beautiful brownish/orange gaseous planet is a Neptunian-type one, and the last planet of the system.


OK, as said previously the two systems are in validation phase, and obviously these two satellites are pretty similar and close to each other, so in the final version I will certainly keep only one.
FYI, the naming in the two planetary systems is temporary until anything is validated and sorted.
So, A4-1 and A4-5 are pretty active with plate and platelet tectonics and they bear a certain form of life, a silicon-based one…


ACen A4-2 isn’t bad too with plate tectonics but no life.


The last planetoid satellite, another pretty active too with volcanic regions.


Now Alpha Centauri B, a K1 Orange Star.


The most notable element is the hot gaseous planet B1 at 0.16 AU from its star…


Among its satellites there are two hot telluric planets depicted above, also pretty active with tectonics and hot in the 330-420 Kelvin range of temperatures.

The rest of its satellites are some metallic asteroids, also pretty hot.


Here comes B2, a telluric planet with ice sheets hydrosphere. It has no tectonic activity at all but a few regions are arid with few and sparse shrubs… The only problem are the deadly winds, but it will be only a details for our courageous colonists! hehe. The atmosphere pressure is thick with 4.7 bars.

This planet has two satellites; one is an icy asteroid, the other one is the planet above. As you can see via its fractures, it has platelet tectonics and so is pretty active and dangerous to set a colony on it.


Next one, B3, is a Saturn-like gaseous planet.
Among its satellites it has one, B3-1 with a pretty strong (in term of life vigor) carbon-based life living in a subsurface ocean. The planet isn’t depicted in screenshot because I must work its surface map.

The other planetoid of B3 is B3-5, a pretty dead and cold world (60-90K) with ice sheets ecosphere and a trace atmosphere.
The rest of the satellites are asteroids.


Finally B-4, the last orbital object of Alpha Centauri B, is a asteroid belt (the bring outer ring in the screenshot above). There aren’t any other screenshots since this belt only contains asteroids.


As you can see, I try the best possible to make the custom maps pretty differents for each others, to keep a certain “individuality” and persona. It’s not easy for the colors and textures, but for the shapes, Fractal Terrains can generate trillions of different seeds, so the possibilities are endless.
And I always check if one generated seed isn’t already used, each time.

In the FARC universe, Alpha Centauri A and B aren’t the homes of any extrasolar faction, at the difference of Epsilon Eridani which is the home of the Magellan Unity. Only the NORAC will have bases in it mainly for military and industrial purposes.
But there are interesting features in these systems; Alpha Centauri A is the only system that have at least one orbital object that carries a basic silicon-based life (basic ie less evolved than the life forms on Earth), which isn’t a small feature when you knows the very tight parameters and calculations for this biochemistry to even exists in the game.
No Earthling-centered astrobiology debate is needed here; after all, scientists some years ago were baffled to find life near the abyssal vents on Earth, because they said and repeated so much time that life in these conditions wasn’t possible… But Nature doesn’t really weight the opinion of these pesky human beings. 🙂

Alpha Centauri B carries, via one of its orbital object, a pretty vigorous carbon-based life, sheltered in a sub-surface ocean.


So that’s all. Once I completed the validation of this dual planetary systems, I will work on the factions’ flags that I have to do and will complete them.

Thanks for your interest, I hope you liked this little show, and have a great Tuesday!
