I wanted to code something similar to *react-three-fiber* but for VueJS.

I started from scratch, I will rewrite some of my [WebGL demos](https://codepen.io/collection/AGZywR) to see if this little toy can do the job.

## Usage (CDN)

TroisJS is really simple and easy to use :

```html
<div id="app">
  <renderer ref="renderer" antialias orbit-ctrl resize="window">
    <camera :position="{ z: 10 }"></camera>
    <scene>
      <point-light :position="{ y: 50, z: 50 }"></point-light>
      <box ref="box" :rotation="{ y: Math.PI / 4, z: Math.PI / 4 }">
        <lambert-material></lambert-material>
      </box>
    </scene>
  </renderer>
</div>

<script type="module">
  import { createApp } from 'https://unpkg.com/troisjs@0.1.12/build/trois.module.cdn.min.js';
  createApp({
    mounted() {
      const renderer = this.$refs.renderer;
      const box = this.$refs.box.mesh;
      renderer.onBeforeRender(() => {
        box.rotation.x += 0.01;
      });
    }
  }).mount('#app');;
</script>
```

## HMR

Thanks to VueJS/ViteJS, **TroisJS use watchers and HMR to update ThreeJS objects when you update a template or a prop**. This means the result in your browser will be automatically updated without reloading all the stuff. **This is really helpful when you are creating a TroisJS Scene**.
