# 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 :
|
|
|
|
|
|
|
|
Initialize with a starting color, a slope vector and a variation vector :
|
|
|
|
![V_{0,0}=\[r_{0,0},g_{0,0},b_{0,0}\]](https://latex.codecogs.com/svg.latex?%5CLARGE%20V_%7B0%2C0%7D%3D%5Br_%7B0%2C0%7D%2Cg_%7B0%2C0%7D%2Cb_%7B0%2C0%7D%5D)
|
|
|
|
![S=\[s_{x},s_{y}\],s_{x}+s_{y}=1](https://latex.codecogs.com/svg.latex?%5CLARGE%20S%3D%5C%5Bs_%7Bx%7D%2Cs_%7By%7D%5C%5D%2Cs_%7Bx%7D+s_%7By%7D%3D1)
|
|
|
|
![K=\[k_{r},k_{g},k_{b}\]](https://latex.codecogs.com/svg.latex?%5CLARGE%20K%3D%5C%5Bk_%7Br%7D%2Ck_%7Bg%7D%2Ck_%7Bb%7D%5C%5D)
|
|
|
|
Given a sigma function as following :
|
|
|
|
|
|
|
|
Compute each pixels with :
|
|
|
|
|
|
|
|
Compute output 3-tuples as color vectors and you have your final image.
|
|
|
|
![V_{x,y}=\[r_{x,y},g_{x,y},b_{x,y}\]](https://latex.codecogs.com/svg.latex?%5CLARGE%20V_%7Bx%2Cy%7D%3D%5C%5Br_%7Bx%2Cy%7D%2Cg_%7Bx%2Cy%7D%2Cb_%7Bx%2Cy%7D%5C%5D)
