# vertices

A buffer of vertex positions for each point in the plane mesh.

```
@property (nonatomic, readonly) const simd_float3 * vertices;
```

## Discussion

Each `float3` value in this buffer represents the position of a vertex in the mesh. The owning plane anchor’s [`transform`](/documentation/ARKit/ARAnchor/transform) matrix defines the coordinate system for these points.

The [`vertexCount`](/documentation/ARKit/ARPlaneGeometry/vertexCount) property provides the number of elements in the buffer.

This buffer, together with the [`triangleIndices`](/documentation/ARKit/ARPlaneGeometry/triangleIndices-1azi3) buffer, describes a  mesh covering the entire surface of the plane. Use this mesh for purposes that involve the filled shape, such as rendering a solid 3D representation of the surface. If, instead, you only need to know the outline of the shape, see the [`boundaryVertices`](/documentation/ARKit/ARPlaneGeometry/boundaryVertices-6nbee) property.
