✨ VueJS 3 + ViteJS + ThreeJS ⚡

I wanted to try to write a lib similar to react-three-fiber but for VueJS.

• 💻 Demos : https://troisjs.github.io/trois/
• 📖 Doc (wip) : https://troisjs.github.io/doc/

I started from scratch... I don't know if I will have time to maintain this, but feel free to participate :)

I will try to rewrite some of my WebGL demos to see if this little toy can do the job.

Trois is a french word, it means Three.

HMR

Thanks to VueJS/ViteJS, TroisJS use watchers and HMR to update ThreeJS objects when you update a template. 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.

Installation

yarn add troisjs

Vue plugin

import { TroisJSVuePlugin } from 'troisjs';
app.use(TroisJSVuePlugin);

PoC

I first made a simple Proof of Concept, take a look at Example1.vue :

<template>
  <Renderer ref="renderer">
    <Camera :position="{ z: 10 }" />
    <Scene>
      <PointLight :position="{ y: 50, z: 50 }" />
      <Box ref="box" :size="1" :rotation="{ y: Math.PI / 4, z: Math.PI / 4 }">
        <LambertMaterial />
      </Box>
    </Scene>
  </Renderer>
</template>

<script>
export default {
  mounted() {
    const renderer = this.$refs.renderer;
    const box = this.$refs.box.mesh;
    renderer.onBeforeRender(() => {
      box.rotation.x += 0.01;
    });
  },
};
</script>
