# vertexCount

The number of vertices in the mesh.

## Declaration

```swift
var vertexCount: Int { get set }
```

## Discussion

Discussion To determine the total data size of a vertex buffer, multiply this value by the stride property of the corresponding layout in the mesh’s vertexDescriptor object.
