Implemented Noise

Worley Noise

• create random points
• value of every pixel is calculated from it's distance to the closest point

You can optimize the algorithm by splitting the screen into sections and the place n (best is 1) point per section.
Then your algorithm to calculate the distance only needs to check the distances with the points in the own section and the 8 surrounding sections.
Otherwise you would need to check every single point...
