you can use a random2f 2d float noise from here:Įdit: I have converted this to C like code Vec2 r = vec2( b ) - f + random2f( p + b ) Īnd here is the same with chebychev distance. Probably 3x3x3 cells and checking gradient. You may ask what the easiest 3d voronoi would be. It divides spaces into a grid, places a dot in each grid cell randomly placed and moves along the grid checking 3x3 cells to find how it relates to adjacent cells. This is the fastest possible - it's a simple voronoi but it looks great. I'm surprised I didn't find this library before now, hence my writing about it here. The library has a proper interface and documentation. This comes with benchmark tests to prove it's accuracy and has great performance. I have not been able to work out exactly how the corruption is creeping in. It mostly works but i'm getting intermittent diagram corruption when dealing with order 10^6 points. The best of the implementations I found online was part of the MapManager program linked from here: I would recommend to test any code you find online extensively with the number of points you expect to use in your finished project before you waste too much time on it. Most have rarely triggered failures when the seed points get very dense.
There's a lot of "nearly correct" C++ code on the internet for implementing Voronoi diagrams.
VORONOI TESSELLATION DEFINITION HOW TO
While the original question asks about how to implement Voronoi, had I found a post that said the following when I was searching for info on this subject it would have saved me a lot of time:
