# data

The data for the geometry source.

## Declaration

```swift
var data: Data { get }
```

## Discussion

Discussion A geometry source’s data is an array of vectors, each of which represents a particular attribute (or semantic) of a vertex in the geometry. The other properties of the geometry source determine how SceneKit interprets this data. For example, an array of vertex positions may have three 32-bit floating-point components per vector, but an array of texture coordinates may have two 8-bit integer coponents per vector.
