xeokit-sdk

npm version CodeSee

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

Resources

Installing

npm i @xeokit/xeokit-sdk

Usage

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 XKTLoaderPlugin to view an XKT model in the browser, which was pre-converted from IFC model from the Open IFC Model Database.

This is just one way to load our models into xeokit: by converting it to XKT and loading via XKTLoaderPlugin. We can also load models from other formats directly, including CityJSON, glTF, LAZ and OBJ.
