Erosion and Continental Drift?
« on: May 07, 2006, 05:24:10 pm »
See title. I wonder if erosion of mountains or continental drift will occur in the game.

That'd be very interesting. Continental Drift would add a whole new element to the game.


And for that reason, I doubt it'll be present. They have to save something for the expansion pack!  ;)

Also, it doesn't fit too well with the terraforming concept.

I doubt you will see either simply because of the time scales you are playing with.  Drift would take millions of years to see a difference but you won't see your whole planet over that time scale.  Erosion is very difficult to model.  Besides, since you can modify planets however you want, it would be difficult to incorporate either aspect into the final design.

And even when you play in a timescale that would be in a way millions of years it still would feel odd. I can see it now how my fishy sporeling is suddenly trap in a inland sea that slowly turn in to a pond and finally in to a mountain chain. Not that fun if you do not evolve fast enough or do not want to evolve to a land creature.

And how do you determine plate motions on a planet with an arbitrary structure?  Ugg the math wouldn't be fun.

Have no idea. But their is a risk i feel that the world might change faster then you expected. The example i gave was only a worst case scenario i think.

What one really should ask one self is what would this add to the game? Is one thing to model the world you self a hole other thing to see it change on it own. And what if i made my wounderfull looking planet, take a spin around the Galaxy and then when i come back it have turn in to a soil eroded dump? Lot of thing to think about when you add a feature like this.

call it a function of rotation and tidal force
crust formed from cooling liquid hot magma radiating heat to a virgin atmospher driving storms and swirling the primordial sea.....

coldest rock is hard and brittle and tends to keep it's shape while warmest rock can change the most auto generate a few upwellings and give the first mega plates brittle cracks and you're half way to drift right there
erosion would create a silt layer and regolithic under layers with suspended rock to play around with
"6.4 Um's per minute" or "The Speed of Wright

The idea is to mix one ingredient that will burn very fast with a second ingredient that will supply enough oxygen for that burning. This burns so fast, it's an explosion.

Yes, texturally it sounds simple.  Now work out the math and programming for that, its no easy business.

From scratch this might be difficult... but they already have programs that scientists use to model this sort of stuff.  Probably wouldn't be any more difficult to implement then some of the tough stuff they've already done.  It's an issue of time and is it within the scope of what they are creating and is it worth the time and effort?

logicly you start with a 2000x1000 point field polar projection with with two circular zones of rotation and a shifting tidal pull stiring it up. as it cools it forms thousands of tiny fragile plates which collect into a few massive plates
which would break and reform around the edges

add in hotspots and you get a fairly good model of plate techtonics

Yeah, i don't really see the point to it.

The only times it would be effecting you would be between each point, say: 1 creature to a tribe, you would just start off in a different place after you got to that point...  Since you aren't controlling eight tribes, it wouldn't make much of a difference.

Then between the transition from tribal to city, it would just be new surroundings.

So why not keep it the same surroundings?

Both are excellent ideas.
