MATHCOMP: Drawland

[Optimus]

I don't know if the deadline is over or this is the last day, but here is my entry anyway. I finished it in a Pentium2 we have here in the army jff. Couldn't post it yesterday because only today I am out of the camp and heading home.

I rewrote from scratch an algorithm I had done in the past in Quickbasic to draw a random land. It used a simple algorithm I know as randomwalk, where there is equal possibility given for a pixel to move up, down, left, right and draw itself again. But here, the drawing was lake adding a small value to the color in the background, like shadebobs, and up limit 255, and an RGB pallete for 0 to 255 colors, from the sea to the white snow. There are also few parameters there, the random walk starts from a point and may teleport back to the starting point after some runs again (the central point of the island) and for few times. According to runs per return back and how many times this repeats, the islands are smaller or bigger.

Then, I decided to map the land to a sphere, like it's the earth and make with some low pass plasma some fuzzy space backround and put some pixel stars. Normally I wanted to improove this parts for blobs for brighter stars and sun, and more stuff, maybe another plannet with bump for moon or so, but time was not enough and I decided to stop here.

Each time you run the programm, a diferrent land is generated.

You're definitely in   Great idea for a demo too!

Nifty stuff Optimus dude

[taj]

Very nice picture, I wondered if anyone would submit a fractal planet. Good job. Amazing you found time given your circumstances! 

[mind]

thats a really neat idea for landscape generation i must say.. and a nice image

karma++

i will so steal that algorithm and use it for something cool in the future

[MrP]

Sweet. Like that, the landscapes look very convincing to... Nice Job

[rdc]

That is very cool.

[Rbz]

Very cool indeed 

[Paul]

Thats wonderfull
If you only look at it fast you think its earth.

[Ghost^BHT]

Looks nice Optimus....well done 

[benny!]

outstanding !!!

[Shockwave]

very, very good indeed! Wow!

You're definitely in :DÃ,  Great idea for a demo too!
Jim

I agree Jim.

Very nice. It reminds me of this great painting I saw one.

Cool! They should use this in Sci-Fi shows for ideas for new planets. I would.

[slinks]

They'd need to add a way of altering the colours, not all land is going to be green and blue, though I could definatly see it being used for something like that

[combatking0]

I'm doing a little sci-fi project myself.

It features eight worlds, and oh now I'm going off topic again.

[Optimus]

Thanks. Well yes, I hope I had time to change a lot of things, like the colors or makng diferrent kinds of surfaces (bumpy surface for moon, firey for sun, plasmoid for diferrent kinds of planets, etc.). It could be a nice thing for a strategy game with maps or space simulator like elite. I am having so many ideas but won't probably code any now. And I was wondering if this kind of making a random land has been used before, it just came out of my mind years ago when I experimented with random walkers in quickbasic. I must still have the old source.
