TresJS

Vue 3 framework for building 3D scenes with Three.js. Declarative components that wrap Three.js objects.

Packages: @tresjs/core (required), @tresjs/cientos (helpers), @tresjs/post-processing (effects)

Installation

# Core (required)
pnpm add three @tresjs/core

# Helpers - controls, loaders, materials, staging
pnpm add @tresjs/cientos

# Post-processing effects
pnpm add @tresjs/post-processing

Quick Reference

Loading Files

Load based on your task:

• references/core.md - TresCanvas setup, composables, events, primitives
• references/cientos.md - OrbitControls, useGLTF, Environment, materials
• references/effects.md - EffectComposer, bloom, glitch, DOF
• references/cookbook.md - Load models, camera setup, animations

DO NOT load all files at once. Load only what's relevant.

Core Concepts

TresCanvas

Root component that creates WebGL renderer and scene:

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

<template>
  <TresCanvas shadows alpha>
    <TresPerspectiveCamera :position="[5, 5, 5]" />
    <TresMesh>
      <TresBoxGeometry />
      <TresMeshStandardMaterial color="orange" />
    </TresMesh>
    <TresAmbientLight :intensity="0.5" />
    <TresDirectionalLight :position="[3, 3, 3]" :intensity="1" />
  </TresCanvas>
</template>

Component Naming

All Three.js classes available as Vue components with Tres prefix:

• THREE.PerspectiveCamera → <TresPerspectiveCamera />
• THREE.Mesh → <TresMesh />
• THREE.BoxGeometry → <TresBoxGeometry />
• THREE.MeshStandardMaterial → <TresMeshStandardMaterial />

Constructor arguments via :args prop:

<TresPerspectiveCamera :args="[75, 1, 0.1, 1000]" />

Reactivity

Props are reactive - changes update the 3D scene:

<script setup>
const color = ref('orange')
const position = ref([0, 0, 0])
</script>

<template>
  <TresMesh :position="position">
    <TresMeshStandardMaterial :color="color" />
  </TresMesh>
</template>

Primitive Component

Inject existing Three.js objects directly:

<script setup>
import { useGLTF } from '@tresjs/cientos'
const { scene } = await useGLTF('/model.glb')
</script>

<template>
  <primitive :object="scene" />
</template>

Available Guidance

references/core.md - TresCanvas props, useTres, useLoop, useGraph, events, performance

references/cientos.md - OrbitControls, useGLTF, useTexture, Environment, Sky, materials, shapes

references/effects.md - EffectComposer vs EffectComposerPmndrs, bloom, glitch, DOF, effect stacking

references/cookbook.md - Load 3D model, camera with controls, animation loop, post-processing
