# FieldOfViewAnchor

An anchor representing a set of field of view (FoV) boundary polygon points in immersive space.

```
struct FieldOfViewAnchor
```

## Overview

This anchor provides polygon points that define preset FoV boundaries, allowing applications
to visualize these FoVs in the immersive space.
