Hello!

I have got a problem with random map generation.

I'm trying to generate a map based on fantastic Perlin noise.

Here my results

And now I want to create only a continent with nearest islands.

I tried to use Gauss function for reducing squares far from center and I tried to use a simple circular reduction for ignoring squares far from center.

Both of this ways gives me a map with good-loking maps, but with circular contour of reduction at edges of reduction zone.

Here an example

I need your opinion to solve this problrm. What another methodics I can use to create best random maps?

I'm using C#.

Thanks in advance!

Denis

P.S. Sorry for my English

Grow/shrink the circle using 1D perlin noise? Make the radius a function of the angle, something like this:

// PerlinNoise1D(x) returns a value in [0, 1]
 
radius = radius * (PerlinNoise1D(angle) + 0.5);

I found a solution that look like good for me.

I 'm creating a radom "fuzzy" rectangle as reduction area/

Here are some examples

And get some maps like that

It looks nice.

Any ideas of improving this algorythm?

Oh, good idea! I will try it and upload here some results.

radius=radius+noise2(x,y)

Oh, thank you so much!
