Simulate an asteroid splitting apart

[kristoffer]

Hi. I just wonder of how to simulate an asteroid splitting apart. How do I make that addon? How do I create the ssc file for it?
It's a big alien solarsystem I am working on, where an asteroid is on a collision course with a gas giant planet.. Before it is reaching it, it is splitting up in parts. And some pieces go that way, some actually heading right towards that gas giant planet.

Would be awesome if anyone could told me that. I have on my own tried to figure out how.

The first thing I would do, which will probably be the most time consuming, is build the asteroid 3d mesh. Then divide it into smaller meshes like a puzzle. Then write your scc file to place all the pieces together. After that i think you will have to do what John said to get the "pieces" to fly apart in different directions.

if you do not have the necessity to orbit the asteroid and the impact is seen from a fixed point of view, you could make use of point sprites only. More colored and volumetric cloud explosion.

It is just that I have trouble creating a xyzv file

This is someway how it will be. These are the 3 pieces that was near collision with a habitable moon around a gas giant planet. There were 3 other pieces which collided with the gas giant planet.
These other 3 pieces came 2000 km above the habitable world's surface. The habitable moon is called Janus, which has a civilization living there, called Alverian.

As I said, it will pass that world.

Yes it is "scheduled" for April 13, 2036 (one chance on 250,000).
Name: Apophis
Size: 325 meters in diameter + / - 15 m
Weight: 27 million tonnes

Path of risk where 99942 Apophis may impact Earth in 2036

Oh NO ! it will NOT go over Yucatan...

It all depends on the accuracy of scientific data.

Asteroid impact of Apophis has been debunked. The chance is 1 of a million.

mhhh, i'm making too a solar system and some things on it are caused by meteors so if someone unhides the explanation please?
respect my solar system the only differences with it are:

the habitable planet has a weird red liquid i saw on the periodic table ( i don't know how it calls in englis)

it's an binary system so, sometimes there's a lot of violence in space

ah, well there are some "eastereggs" and most of them are explained by meteors

also there's an advanced supernova explosion around the star system, and the aliens there are called Nemesians (their planet is called Nemesis)

there also is an extint race: the planet was sighlty like the earth but a giant meteor hitted the planet not much ago (3 years) leaving a giant lava crater wich is visible even today

That liquid is called bromine (Br), but remove it if you want your planet to be habitable. Bromine is poisonous.

I have a stupid idea that might work.

Design five small cmod files that fit together, the closer the better, but they do have to be seamless.
Then make each one an xyzv file that puts them in sync until they reach the roche limit.
At that time they can diverge based on their position and mass in the conglomerate.
The individual pieces will have different roche limits of their own, and so might break up yet again.

Roche Limit is the point where two objects gravity equal each other, and surface components can come loose.
This can be gravel, or pieces of the smaller object if there are faults where internal structural strength is exceeded by external gravity.
It can also be compared to tidal force if part of an object is inside the roche limit, but not all of it.

For a guide on how to construct it, look up any addons or nasa data on Shoemaker-Levy 9, and its impact with Jupiter.

Good luck.
