MarbleGenerator

Need to be refactored to use maven

Generate a marble-like pattern to use in wallpapers.

Usage :

java -jar MarbleGenerator.jar [output file name] [width] [height] [size]

Optional arguments :

1 output file name :
- name of the output file (without extension)
- default is "wallpaper"
2 width :
- width of image (square if no other arguments)
- default is your screen width
3 height :
- height of image
- default is your screen height
4 size :
- size of individual squares in the image
- default is random between 3 and 12

It gives you something like this :

Theory

Generate a matrix of random 3-tuples as following :

$-1<R_{x,y,z}<1$

Initialize with a starting color, a slope vector and a variation vector :

$V_{0,0}=[r_{0,0},g_{0,0},b_{0,0}]$

$S=[s_{x},s_{y}],s_{x}+s_{y}=1$

$K=[k_{r},k_{g},k_{b}]$

Given a sigma function as following :

$0<\sigma (x)<1$

Compute each pixels with :

$V_{x,y,z}=\sigma (R_{x,y,z}*K_{z}+V_{x-1,y,z}*s_{x}+V_{x,y-1,z}*s_{y})$

Compute output 3-tuples as color vectors and you have your final image.

$V_{x,y}=[r_{x,y},g_{x,y},b_{x,y}]$
