# CATransform3D

The standard transform matrix used throughout Core Animation.

```
struct CATransform3D
```

## Overview

The transform matrix is used to rotate, scale, translate, skew, and project the layer content. Functions are provided for creating, concatenating, and modifying CATransform3D data.
