Svelte Depth 3d Component

svelte component to show a fake 3d image with depth map

svelte depth 3d component

Display an image with a fake 3D effect, using a depth map. Made for svelte, using threlte, threejs and tailwindcss. Still a work in progress, but usable.

Try the demo here.

How to use

  1. Copy and paste the src/lib/Depth3D/ folder of this repository into your svelte projects src/lib/ folder.
  2. Install tailwindcss and threlte (core and extras) (work through their setup or see below for commands)
  3. Get an image and generate a accompanying depth map, for example using zoedepth
  4. Use the Depth3D component in your pages directly like so:
<script>
  // Depth3D example
  import Depth3D from '$lib/Depth3D';
</script>

<!-- will adjust to the parents size/position -->
<Depth3D
    image={{
        image: 'your-image.png',
        depth: 'your-depth.png'
    }}
/>

Which images work well

This effect only simulates 3D, so some images will show weird artifacts. Portraits with a single person in the middle tend to work well. The effect will also depend on the quality of the depth map. Some trial and error might be necessary to get the desired effect.

Installing the dependencies

TailwindCSS (assuming you created your svelte app with the svelte create command)

  1. Install
    npm install -D tailwindcss postcss autoprefixer
    npx tailwindcss init -p
    
  2. Update your tailwind.config.js file to find files with tailwind classes:
    content: ['./src/**/*.{html,js,svelte,ts}'],
    
  3. Create a app.css file in your src folder.
    @tailwind base;
    @tailwind components;
    @tailwind utilities;
    
  4. Import the css file in your +layout.svelte file ```svelte
```

Threlte (core and extras)

  1. Install
    npm install three @threlte/core \
             @threlte/extras \
             @types/three
