Babylon.js Viewer

Display 3D models on your webpage

The Babylon.js viewer is the simplest way to display 3D content on a web page.

To display a 3D model on you web page:

  1. Add a script reference to the viewer

    <script src=""></script>
  2. Add a <babylon> tag and set the model attribute to point to a .gltf or .glb file

    <babylon model="model.gltf"></babylon>

    We recommend using the glTF format (.gltf or .glb) for displaying 3D models on your webpage. Other formats supported by Babylon.js loaders are also supported by the viewer component including .babylon, .obj, and .stl formats.

The Babylon.js viewer automatically provides a default viewing experience for 3D models. All aspects of this experience are configurable. See Configuring the viewer for more information on customizing the viewing experience.


See the Pen Babylon.js Viewer - Display a 3D model by Babylon.js (@BabylonJS) on CodePen.


Controlling the size of the viewer is one of the most common configuration operation. It is rather easy as the viewer in default mode will fill 100% of the width and height of its container. So in order to control the viewer, you can simply style its encclosing container.

See the Pen Babylon.js Viewer - Resize the viewer by Babylon.js (@BabylonJS) on CodePen.
