Voronoi

The Voronoi diagram is based on the idea of assigning ownership of points in space to their closest seed point, according to some distance function. The Voronoi diagram is the dual of the Delaunay triangulation.

Vector Fields

Here are some examples of particles being released onto vector fields. The particles have momentum and the vector fields apply forces. I experimented with various ways to generate vector fields - standard Perlin noise, spirals, bowls, and most interestingly a “Voronoi” vector field where each Voronoi cell is its own small spiral field. I composed these fields together in many of these examples.
