Orillusion次时代 WebGPU 引擎

Orillusion 次时代 WebGPU 引擎

官网: https://www.orillusion.com/
教程: https://www.orillusion.com/guide/
Orillusion 引擎是一款完全支持 WebGPU 标准的轻量级渲染引擎。基于最新的 Web 图形API标准,我们做了大量的探索和尝试,实现了很多曾经在 Web 中很难实现或者根本实现不了的技术和功能。我们自己从以下几个方面对引擎的架构和功能特点做出了总结。

使用之前需要安装最新的Chrome/Edge浏览器
还需要安装python3

第一个demo

1. 编写index.html

在本地文件夹Orillusion下新建index.html,把如下代码粘进去

DOCTYPE html>
<html>

<head>
	<meta charset="utf-8">
	<title>1My first Orillusion apptitle>
	<style>
		body {
			margin: 0;
		}
	style>
head>

<body>
	
	<script type="importmap">
	{
	  "imports": {
		"@orillusion/core": "https://unpkg.com/@orillusion/core/dist/orillusion.es.js",
		"@orillusion/stats": "https://unpkg.com/@orillusion/stats/dist/stats.es.js"
	  }
	}
	script>
	
	<script type="module">

		import { Engine3D, Scene3D, Object3D, Camera3D, LitMaterial, BoxGeometry, MeshRenderer, DirectLight, HoverCameraController, View3D, AtmosphericComponent } from '@orillusion/core'
		import { Stats } from "@orillusion/stats"

		async function demo() {

			// initializa engine
			await Engine3D.init()
			// create new scene as root node
			let scene3D = new Scene3D()
			// add an Atmospheric sky enviroment
			let sky = scene3D.addComponent(AtmosphericComponent)
			sky.sunY = 0.6
			// create camera
			let cameraObj = new Object3D()
			let camera = cameraObj.addComponent(Camera3D)
			// adjust camera view
			camera.perspective(60, Engine3D.aspect, 1, 5000.0)
			// set camera controller
			let controller = cameraObj.addComponent(HoverCameraController)
			controller.setCamera(0, 0, 15)
			// add camera node
			scene3D.addChild(cameraObj)
			// create light
			let light = new Object3D()
			// add direct light component
			let component = light.addComponent(DirectLight)
			// adjust lighting
			light.rotationX = 45
			light.rotationY = 30
			component.intensity = 1
			// add light object
			scene3D.addChild(light)
			// create new object
			const obj = new Object3D()
			// add MeshRenderer
			let mr = obj.addComponent(MeshRenderer)
			// set geometry
			mr.geometry = new BoxGeometry(5, 5, 5)
			// set material
			mr.material = new LitMaterial()
			// set rotation
			obj.rotationY = 45
			// add object
			scene3D.addChild(obj)
			// create a view with target scene and camera
			let view = new View3D()
			view.scene = scene3D
			view.camera = camera
			// start render
			Engine3D.startRenderView(view)

		}
		demo()

2. python运行简易服务器

命令行运行如下命令 -d 后面跟本地文件夹路径

python -m http.server 9000 -d D:\chenchao\web3dprojects\Orillusion

3. 用Edge浏览器打开http://127.0.1.1:9000/
