# Dot Screen

</DocsDemo>
6+
7+
The `DotScreen` effect is part of the [`postprocessing`](https://pmndrs.github.io/postprocessing/public/docs/class/src/effects/DotScreenEffect.js~DotScreenEffect.html) package. It allows you to create a dot screen effect, providing flexibility for artistic effects.
8+
9+
## Usage
10+
11+
The `<DotScreenPmndrs>` component is straightforward to use and provides customizable options to fine-tune the dot screen effect.
12+
13+
```vue{4,13-16,42-46}
14+
<script setup lang="ts">
15+
import { ContactShadows, Environment, OrbitControls, useGLTF } from '@tresjs/cientos'
16+
import { TresCanvas } from '@tresjs/core'
17+
import { DotScreenPmndrs, EffectComposerPmndrs } from '@tresjs/post-processing'
18+
import { NoToneMapping } from 'three'
19+
20+
const gl = {
21+
clearColor: '#ffffff',
22+
toneMapping: NoToneMapping,
23+
multisampling: 8,
24+
}
25+
26+
const effectProps = reactive({
27+
angle: 1.57,
28+
scale: 1.25
29+
})
30+
31+
const { scene } = await useGLTF('https://raw.githubusercontent.com/Tresjs/assets/main/models/gltf/suzanne/suzanne.glb', { draco: true })
32+
</script>
33+
34+

45+
46+
<ContactShadows
47+
:opacity="1"
48+
:position-y="-1.5"
49+
/>
50+

52+
<Environment preset="modern" />
53+
</Suspense>

</TresCanvas>
61+
</template>
62+
```
63+
64+
## Props
65+
66+
| Prop | Description | Default |
67+
| -------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------ |
68+
| **angle** | The angle of the dot pattern *(in radians)*. | `1.57` |
69+
| **scale** | The scale of the dot pattern. | `1.0` |
70+
| **blendFunction** | Defines how the effect blends with the original scene. See the [`BlendFunction`](https://pmndrs.github.io/postprocessing/public/docs/variable/index.html#static-variable-BlendFunction) options. | `BlendFunction.NORMAL` |
71+
72+
