# PHASEShape

A collection of points that connect to form a 3D volume.

## Declaration

```swift
class PHASEShape
```

## Mentioned in

Playing sound from a location in a 3D scene

## Overview

Overview To define your scene’s important 3D volumes, create one or more of the following surfaces and add them to your scene’s shapes array: The audio-emitting surface of a volumetric PHASESource The audio-deflecting surface and texture of a PHASEOccluder
