If you are developing an 8th Wall project with [Studio](https://8thwall.org/docs/studio), the 8th Wall Engine is included in all projects by default and does not require additional setup.

The 8th Wall AR Engine is a complete implementation of 8th Wall's Simultaneous Localization and Mapping (SLAM) engine, hyper-optimized for real-time WebAR on browsers. AR features include World Tracking, Image Targets, Face Effects, and Sky Segmentation.

The engine is built-in to Studio projects, and is also easily integrated into modern 3D JavaScript frameworks such as [A-Frame](https://aframe.io/), [three.js](https://threejs.org/), [PlayCanvas](https://www.playcanvas.com/), and [Babylon.js](https://www.babylonjs.com/).
