This project is using Percy.io for visual regression testing. npm version

xeokit is a JavaScript software development kit from xeolabs for viewing high-detail, full-precision 3D engineering and BIM models in the browser.


npm i @xeokit/xeokit-sdk


The xeokit SDK lets us develop our own browser-based BIM viewer, which we can fully customize and extend with plugins. Let’s create a Viewer with a WebIFCLoaderPlugin to view a IFC model in the browser, then view a sample IFC model from the Open IFC Model Database.
