Installation

Learn how to install TresJS

pnpm

pnpm add three @tresjs/core

npm

npm install three @tresjs/core

yarn

yarn add three @tresjs/core

Better use with Vue 3.x and composition API

Typescript

TresJS is written in Typescript and it's fully typed. If you are using Typescript, you will get the full benefit of the typings. Just make sure you install the types for three.

npm

npm install @types/three -D

yarn

yarn add @types/three -D

pnpm

pnpm add @types/three -D

Getting started

You can install TresJS as any other Vue plugin

import { createApp } from 'vue'
import Tres from '@tresjs/core'
import App from './App.vue'

export const app = createApp(App)

app.use(Tres)
app.mount('#app')

Or you can use it directly in your component

<script setup lang="ts">
import { TresCanvas } from '@tresjs/core'
</script>

<template>
  <TresCanvas>
    <!-- Your scene here -->
  </TresCanvas>
</template>

TIP

This is recommended for performance and bundle size reasons, tree-shaking will work better and you will only import the components that you use.

Vite

Since v2 is a custom renderer, we need to let the vue-compiler of your app know that the components of Tres are ok to be included to avoid the [Vue warn]: Failed to resolve component warning.

You just need to import and add the templateCompilerOptions from TresJS to your vite.config.ts inside of the vue plugin:

import { templateCompilerOptions } from '@tresjs/core'

export default defineConfig({
  plugins: [
    vue({
      // Other config
      ...templateCompilerOptions
    }),
  ]
})
