# projectionMatrix

A transform matrix appropriate for rendering 3D content to match the image captured by the camera.

```
var projectionMatrix: simd_float4x4 { get }
```

## Discussion

Reading this property’s value is equivalent to calling the `projectionMatrix(withViewportSize:orientation:zNear:zFar:)` method, using the camera’s [`imageResolution`](/documentation/ARKit/ARCamera/imageResolution) and [`intrinsics`](/documentation/ARKit/ARCamera/intrinsics) properties to derive size and orientation, and passing default values of `0.001` and `1000.0` for the near and far clipping planes.
