I've been working on tweaking the code found in this particular example:
How to connect Threejs to React?
This is the snippet of code I am focusing on:
import React, { Component } from 'react'
import * as THREE from 'three'
class Scene extends Component {
constructor(props) {
super(props)
this.start = this.start.bind(this)
this.stop = this.stop.bind(this)
this.animate = this.animate.bind(this)
}
componentDidMount() {
const width = this.mount.clientWidth
const height = this.mount.clientHeight
const scene = new THREE.Scene()
const camera = new THREE.PerspectiveCamera(
75,
width / height,
0.1,
1000
)
const renderer = new THREE.WebGLRenderer({ antialias: true })
const geometry = new THREE.BoxGeometry(1, 1, 1)
const material = new THREE.MeshBasicMaterial({ color: '#433F81' })
const cube = new THREE.Mesh(geometry, material)
camera.position.z = 4
scene.add(cube)
renderer.setClearColor('#000000')
renderer.setSize(width, height)
this.scene = scene
this.camera = camera
this.renderer = renderer
this.material = material
this.cube = cube
this.mount.appendChild(this.renderer.domElement)
this.start()
}
componentWillUnmount() {
this.stop()
this.mount.removeChild(this.renderer.domElement)
}
start() {
if (!this.frameId) {
this.frameId = requestAnimationFrame(this.animate)
}
}
stop() {
cancelAnimationFrame(this.frameId)
}
animate() {
this.cube.rotation.x += 0.01
this.cube.rotation.y += 0.01
this.renderScene()
this.frameId = window.requestAnimationFrame(this.animate)
}
renderScene() {
this.renderer.render(this.scene, this.camera)
}
render() {
return (
<div
style={{ width: '400px', height: '400px' }}
ref={(mount) => { this.mount = mount }}
/>
)
}
}
export default Scene
I have been attempting to adjust the canvas size to fit the full viewport height and width for background purposes.
In my progress, I decided to utilize the npm package
npm install react-native-responsive-view-port --save
and made the following modifications:
render() {
return (
<div
style={{ width: vh(100), height: vw(100), }}
ref={(mount) => { this.mount = mount }}
/>
)
}
Despite trying to make it responsive using percentages, I encountered the error:
Module not found: Can't resolve 'react-native-expo-viewport-units' in 'C:\Users\Gabriel\Desktop\grid_site\src\pages'
If anyone has a solution to help me achieve a responsive layout with Three Js canvas spanning the entire browser window, I would greatly appreciate it!
