Vue 3 component for quickly adding a ThreeJS scene.

npm install three vue3-three-wrap

Then, in your Vue component:

<template>
    <ThreeWrap :start="start" :update="update" />
</template>

<script setup lang="ts">
    import { ThreeWrap, Vue3ThreeWrap } from 'vue3-three-wrap'
    import * as THREE from 'three'

    // build a box
    const box = new THREE.Mesh(
        new THREE.BoxGeometry(),
        new THREE.MeshBasicMaterial({ color: 'blue' })
    )
    box.position.z = -5

    // add the box
    // `start` runs once when the scene is ready
    const start: Vue3ThreeWrap.Start = (opts) => {
        opts.scene.add(box)
    }

    // rotate the box
    // `update` runs once per frame
    const update: Vue3ThreeWrap.Update = () => {
        box.rotation.y -= 0.0166
    }
</script>
