# Lens Distortion
2+

<LensDistortionDemo />

</DocsDemo>
6+
7+
The `LensDistortion` effect is part of the [`postprocessing`](https://pmndrs.github.io/postprocessing/public/docs/class/src/effects/LensDistortionEffect.js~LensDistortionEffect.html) package. It allows you to apply a lens distortion effect to your scene, providing flexibility for creating realistic camera effects.
8+
9+
## Usage
10+
11+
The `<LensDistortionPmndrs>` component is straightforward to use and provides customizable options to fine-tune the distortion effect of your visuals.
12+
13+
```vue{3,12-17,52-56}
14+
<script setup lang="ts">
15+

27+
principalPoint: new Vector2(0.0, 0.0),
28+
focalLength: new Vector2(0.5, 0.5),
29+
skew: 0,
30+
}
31+

## Props
75+
76+
| Prop | Description | Default |
77+
| -------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------ |
78+
| **distortion** | The distortion effect strength. <br> Accepts `Vector2` or `[number, number]`. | `[0.0, 0.0]` |
79+
| **principalPoint** | The center point. <br> Accepts `Vector2` or `[number, number]`. | `[0.0, 0.0]` |
80+
| **focalLength** | The focal length. <br> Accepts `Vector2` or `[number, number]`. | `[1.0, 1.0]` |
81+
| **skew** | The skew value. | `0` |
82+
83+
