Latest stuff:

a quick preview of the inhabitants

the house design program

their houses (half procedurally/half designed in program above)

and the trees

with a  working tech-demo (windows)

Currently i am working on the houses again (the roofs notably), and tweaking alot of numbers in the plant/tree department

original post:
Hello!
I am trying to build a procedural planet.
At the moment i'm working on the different biomes.
and other planet size problems

There will also be a more human scale view with generated vegetation and stuff.
I'll try to keep you updated.

How are you doing rivers?

[Epitaph64]

That looks pretty awesome so far! At first glance, I thought it was some kind of liero style procedural platformer, and then I realized it wasn't... Haha, anyways, good luck!

[nikki]

How are you doing rivers?

Not properly yet , when the river can't flow lower it should form a lake and rise, until it finds a spot to go again.
This isn't implemented yet..
i don't really understand why so many river are perfectly diagonal, but i am sure i'll suss it out !

[st33d]

Am I wrong in thinking that the rivers should be implicitly described by the water level constant?

Certainly water eats away at the rock, but that's why we have gulfs. Those rivers should be hungrier for land where they meet the sea.

[nikki]

the rivers are a bit better:

at st33d:
am i right in thinking you are talking about the forming of a riverdelta?

[Hempuli‽]

Looks wonderful!

[nikki]

Hello again !
I was strugling with meaningful color values for the world map, now i've found this lovely triangle :

And I've also started with the closer view screens:

^{this would be a temperate decidious place, or maybe boreal!, imagine trees here}

todo list

-soil types
-generative vegetation
-rivermaking at this viewlevel
-designing small 16x16 textures for the different biomes' soil (definined in triangle above)

[Hempuli‽]

It looks great, but what are those tiny dark rectangles around the landscape?

[nikki]

my tileset is not completely finished, and i threw in some rectangles to see where the 'holes' were, next update they will be gone !

[Super Joe]

Hello this is Superjoe

Biome is a cool word that only appears in cool games.

[increpare]

looking very cool!

You should team up with Ullillilia

I am also wrestling with procedural stuff. My head is buzzing from all the porting of various algorithms to Ruby language (Perlin, Simplex and Diamond-Square noise). Still trying to figure out how to make it generate a somewhat acceptable world (with continents and stuff), so I wonder what are you using there.

[nikki]

Hi Mipey

For the forming of continents i found the
 Voronoi Diagram very helpfull !

I like to try to explain what it does, so here i go:
The Voronoi Diagram is a way to divide a 2dimensional square or rectangle into funnily formed shapes, or polygons . Mind you the voronoi step in my program is the computational heaviest (atm it takes about 1/2 of the total time the forming need !)
There is some of tweaking involved.

In my case the basic world recipy is :

• 0.6 Diamond Square
• 0.4 Voronoi

a few cycles of extra rounding and some stirring with noise, and leave it cook for as short a time as possible  

I hadn't looked into the Simplex stuff before, and I thank you for mentioning it. Thru Wiki I found
 this PDF   but are you cabale of explaning what it is , in an easier way ?

anyway Succes ! and bye

[Mipe]

Trust me, I don't know it any better than you do. In the end I've had a friend help me with fractal noise (perlin), he did most of the work there. However, since I want seamless tiling world (say, 32x32 world map, each cell is a 128x128 region, each of region cells is a 128x128 local area or something, transition between areas and regions is supposed to be seamless).  But that is proving to be quite troublesome for my limited abilities...

You can see noise algorithm implementations in Ruby here. Currently I'm using the Fractal Noise, because that's at least supported by my more capable friend, I probably should use Diamond-Square displacement, however I haven't figured out how to make it tile yet.

Hell, I'm not even getting continents yet.  

Such is the price of freedom, huh?

P.S.: Fix the PDF url, but yeah, that's what I followed when I attempted to integrate Simplex noise. Apparently with Simplex you can easily create an EVOLVING planet, that is animating its transitions. Imagine watching Earth go from ancient Pangaea to the continents we are familiar with nowadays. But hey, that's rocket science for me. Imagine a roguelike with time travel capability!

O.k !

Next up , The vegetation

in Another Thread I'm finding out about ways of growing vegetation procedurally, and have started experimenting.

I was wondering wat the result would be if you have a very high recusirveness,
And in case your wondering too....

I present to you " The Hairy Ball" 

oh and btw , at Moi : I am trying to find that specific member of the board, but i can't find it , who is Ullillilia ?

[moi]

He's not on that board, he's just an autistic kid who create games and who spends a crazy long time obsessing about details of the worlds he creates.
Look for him on youtube.
For some reason, this picture reminded me of the type of stuff he creates.

[nikki]

His terrain does look very good !
I just put the hairy ball aside,   
And applied the proper angle calculations,

Immediatly there was this little forrest on my screen
