What is Voronoi Noise?

Показать описание
In this GLSL shader tutorial, we will go over Worley (or Voronoi) noise. We start by setting up a GLSL shader in VS Code. Then we create a grid of cells and get the distance to the edge of each cell to display a uniformly distributed Voronoi shader. Then we randomize the points on each cell to display an organic cell-like structure. Finally, we invert the shader to make it look like clouds.

Great explanation and break down. Looking forward to more of these!

in my opinion, this is a better example of cellular noise not so much Voronoi noise. I would think that Voronoi noise is the distance to the Voronoi diagram at any given point.

But disappointing you didn’t go into the differences of Voronoi vs Worley and continue building it from the Voronoi into a true Worley. (The difference as I understand it is that Worley ignores the initial starting grid and just has a random distribution of points, and the pixel’s value is the distance to the closest point. I think it also uses some sort of radius to check within to optimize)
