# frequency

A value that determines the number and size of cells in generated noise.

## Declaration

```swift
var frequency: Double { get set }
```

## Discussion

Discussion A Voronoi noise source generates a field of noise values by randomly picking seed points at random positions in a space, then dividing the space into cells so that all the points in a cell are closer to that cell’s seed point than to any other seed point. Increasing frequency increases the number of seed points in any given unit area of a generated noise map, thus also decreasing the size of the cells that surround them. The default value is 1.0.
