Impresing! nicely fit in 4kb  .
Is the road based on splaines/bezier?

oh no, it's a distorted line (perlin noise based distortion).
very nice application of perlin noise - not just for pattern filling .
so tell us more about fractal terrain generation. how did u do it?
(julia/mandelbort based hight map? but I supposed u used some other fracs).
Sincerely,
Turms

Wow!
Very nice indeed, Inigo! =)
(or, as someone dear to me would've said: Impressive. Most impressive...

turm, the heightmap (well, there is not any map, not even in memory,
so you can move as far as you want on the terrain) is a fractal sum of
perlin noises (so called fbm). I did modify it a bit so it gets
modified by it's own derivatives. More info here:
http://www.rgba.org/iq/computer/articles/morenoise/morenoise.htm
Clouds, grass distribution, moon pattern, and other details are also
fbm. |

oh, I forgot, I made a video too http://www.rgba.org/iq/fractals/videos/fbm_video_03.avi
On the video some level-of-detail artifacts are visible (the amount of
iterations is based on the distance so far away parts of the fractal
alias less, but I forgot to smoothly interpolate between iteration
count, hence you have some banding.. next time it will be fixed) |

Very interesting indeed. And a very nice work and the web page .

Hi Inigo, what codec did you use ? - I get no picture in MediaPlayer.

DivX 6 if I remember well. It quite standard today, you can download
it from http://www.divx.com if you don't have it. |

Thanks - I've never got around to installing DivX |
