Orillusion is a pure Web3D rendering engine which is fully developed based on the WebGPU standard.

Note:

Currently, this repo is used to collect feedback on the NPM package of the Orillusion engine. According to all the feedback, we will carry on refining the engine core. Then, we need to set up the regulations for a long-term open source project and all the source code will be put in this repo in the near future, which indicates a brand new journey for Orillusion.

Orillusion

Orillusion is a pure Web3D rendering engine which is fully developed based on the WebGPU standard. It aims to achieve desktop-level rendering effects and supports 3D rendering of complex scenes in the browser.

Need to know

Beta version, NOT recommended for any commercial application.

Install

NPM

We recommend using front-end build tools for developing Web3D applications, such Vite or Webpack.

• Install dependencies:

npm install @orillusion/core --save

• Import on-demand:

import { Engine3D, Camera3D } from '@orillusion/core'

• Import globally:

import * as Orillusion from '@orillusion/core'

CDN

In order to use the engine more conveniently, we support to use native <script> tag to import Orillusion. Three different ways to import using the official CDN link:

• Global Build: You can use Orillusion directly from a CDN via a script tag:

<script src="https://unpkg.com/@orillusion/core/dist/orillusion.umd.js"></script>
<script>  
    const { Engine3D, Camera3D } = Orillusion  
</script>

The above link loads the global build of Orillusion, where all top-level APIs are exposed as properties on the global Orillusion object.

• ESModule Build: We recommend using the ESModule way for development. As most browsers have supported ES module, we just need to import the ES build version of orillusion.es.js

<script type="module">  
    import { Engine3D, Camera3D } from "https://unpkg.com/@orillusion/core/dist/orillusion.es.js" 
</script>

• Import Maps: In order to manage the name of dependencies, we recommend using Import Maps

<!-- Define the name or address of ES Module -->  
<script  type="importmap">  
{  
    "imports": { "@orillusion/core": "https://unpkg.com/@orillusion/core/dist/orillusion.es.js" }  
}  
</script>  
<!-- Customerized names could be imported -->  
<script  type="module">  
    import { Engine3D, Camera3D } from "@orillusion/core"
</script>

Usage

Create Engine3D instance

At the beginning, we need to use Engine3D.init() and then the instance Engine3D will be created for further use

import { Engine3D } from '@orillusion/core' 
Engine3D.init().then(()=>{  
    // Next
})

As Engine3D.init() is asynchronous, we recommend using async/await in the code

import { Engine3D } from '@orillusion/core'  
async function demo(){  
    await Engine3D.init();  
    // Next 
}  
demo()

Create canvas

In default, Engine3D.init()will create a canvas the same size with the window. Also, we could create a canvas manually using tag <canvas> with a id

<canvas id="canvas" width="800" height="500" />

Next, we need to get the <canvas> via id and then init engine by passing the <canvas> to canvasConfig

import { Engine3D } from '@orillusion/core';  
let canvas = document.getElementById('canvas')  

await Engine3D.init({  
    canvasConfig: { canvas }  
})
