Interactive planet-creation tutorial

[Ramiel]

And now we can see the "planet master" at work...
Ladies and gentlemen, this is one of the steps that our aszazeroth is doing to make another brilliant planet in his collection, below us you can clearly see a meteor crater... Later, our crew will bring you the dinner, enjoy the ride.

An Oxygen-rich atmosphere is also somewhat corrosive. Rust is the oxidation of metals. Fire is fast or rapid oxidation. (So, I guess techncially fire is real fast rust!)
I dont think there will be much industry on a planet with that much O2. I dont think a planet would form with that much oxygen.

The planet gas composition came out of a small program that I used on to "generate" solar systems. It sort of accretes matter from a pseudo-proto-stellar nebula to form the star (input parameter) and a host of planetary bodies with a lot of physical parameters (output table). Basically gravity and location from the star will determine what gases are "trapped" in the gravity well and for this particular case, apparently a lot of oxygen was trapped. I agree with the highly corrosive nature of the atmosphere. In pure O2 atmospheres aluminum bars burn like wodden logs (ref: a cool NASA movie I saw once).

To compensate for this, I will make the colony and industry sub-surface and sub-terranian or habitat structured. The overall gain here is the pure deposits of precious metals that can be extracted with minimal refinery. For some more spice to the story we can speculate if the roid actaully was natural or they are mining the wreckage of an alien spaceship

Thanks ALL for the nice comments.

Newest step done. We want more!

Indeed we do.

This is really cool!

Oh, BTW... the plugin works for GIMP too.

Go here. for more info.

Thanks mate for this tutorial (and pointing me to the planet map gen!).

So, time to make some colors for the lad. As we discovered before, the planet has a highly oxidizing atmosphere so I went looking for oxidized rock in my old geology books. Using the alpha channel for selection I the painted blotches of color, starting with larger brushes, then smaller and smaller. Some distorting filters and then more painting. Finally I did get something that looked like a nice -base- palette.


Fig 5.1 : Base palette or surface colors.

Time to do a test-drive in your're favorite 3D application again, to check out the size of features.


Fig 5.2 : Test-render.

Note... there are still ways to go here, but the overall size of things looks promising. Now where are those W.I.P threads ?!

Not much to show yet

What distortion filters did you use?

Hmm, damn good question... been so many planets and I tend to work on some in parallel these days. For this it looks like some kind of ripple, blur and sharpen, then re-painting some of the harder edges away. Not anything fancy, just something to break up the colors and to get a palette to work from. The real work is still ahead.... and not to mention the cloud map which may even be another tutorial all together.

[Lt. Cannonfodder]

Thanks, looks like I have a few hours of worth of painting ahead of me. The joy!

As for clouds, I might go lazy and just stick with some premade cloudsmaps

[Ozylot]

Oooo... more please.
