Sej

Sej [ˈsɛj]. ("say") is a game engine for the web. It's heavily inspired by three.js's editor.

Sej is:

• High-performance
• Flexible
• Very opinionated (!)

It supposed to be a batteries included game engine that allows you to create performant 3D scenes with ease. However, it's not production ready yet!

Getting started

Begin by installing sej:

yarn add sej
Copy

Use the SEJ namespace to avoid conflicts with other libraries:

import * as SEJ from 'sej';
Copy

Building your own Sej

The Sej engine consists of multiple parts. You are free to pick and choose which parts you want to use. This will determine how your application will look and behave.

To aid you with this, there are some factories that you can use to build your own Sej:

const factory = new AbstractExampleFactory();
const sej = factory.build();
Copy

The variable sej will now contain a engine that has all the bells and whistles that you need to create simple scene.
