# vertices

The vertices of the mesh.

## Declaration

```swift
var vertices: ARGeometrySource { get }
```

## Discussion

Discussion The count equals the total number of vertices. Since each vertex is the type SIMD3<Float>, componentsPerVector is three. The following code demonstrates retrieving a vertex at a particular index. extension ARMeshGeometry {      func vertex(at index: UInt32) -> SIMD3<Float> {         assert(vertices.format == MTLVertexFormat.float3, "Expected three floats (twelve bytes) per vertex.")         let vertexPointer = vertices.buffer.contents().advanced(by: vertices.offset + (vertices.stride * Int(index)))         let vertex = vertexPointer.assumingMemoryBound(to: SIMD3<Float>.self).pointee         return vertex     } }
