Shift click the green flag (to decrease the generation time). Click to place points then hit the space bar to start the generation. The generation time scales with the amount of points however you can get away with under 50 without any lag issues. Most I have done is 200 which took 15+ minutes to render. The generation will start with the x-axis to generate the colors and outlines. it will then generate around down the y-axis to refine the outlines.
I am using a modified version of ChewieTest's sorting algorithm. The rest is done by me. What a voronoi diagram is: https://en.wikipedia.org/wiki/Voronoi_diagram What i will be adding in the future: -the ability to save pictures -more color algorithms -faster generation time (more optimized sorting algorithm) -more refined border lines
