import { createGlowField } from "slides:particles/GlowField";

export const field = createGlowField({particleCount: 1536});

# Glow field

<View style={{ width: 1696, height: 650 }}>
<TypeGPUShader code={field.program} particleCount={field.particleCount} particles width={1696} height={650} />
</View>
```
