texture generating script

[vh]

you'll need python 2.7
http://www.python.org/download/releases/2.7.3/
PIL
http://www.pythonware.com/products/pil/ (most recent version)
noise module
http://www.lfd.uci.edu/~gohlke/pythonlibs/#noise
and the script

just extract the folder somewhere but do not take stuff out of the folder. run 'runthis.py'.

Can you share an example of what this generates?

pics or virus

Just kidding but I'm curious of what it results in.

[vh]

yeah sure but i warned you they're not exactly perfect yet...

Looks early in development, but still quite cool.

Did anyone here see v1 of Universe Sandbox? It was quite early in development too.

How did you put the script together? Did you base it on some existing code?

[vh]

well it uses a python image module, but besides that i wrote it from scratch. it's very simplistic actually: it selects a random point, then picks another random point nearby, and so on. then it draws a polygon by connecting all of the points. it draws three polygons (although they look like one large blob at this stage).

i've seen (and used) universe sandbox 1 before

i've updated it and it now uses simplex noise to generate continent-like shapes

you'll need to install http://www.lfd.uci.edu/~gohlke/pythonlibs/#noise (appropriate version of noise) but it's quite trivial just click the next button a few times

the edges don't quite match up yet though

updated. download link is the same as the on in op.

i used three dimensional noise and this solves the problem of making the texture seamless as well as distortion near the poles

now make distance from blue affect the land color
(get redder towards the center, greener towards the blue)
