This tutorial shows the 3D models that are used by the Demo Application.

The ModelWidget API is used to display and inspect the 3D models, demonstrating the following aspects:

  • Node hierarchy of 3D models

  • Octree generation for 3D models

  • Spatial queries on 3D models

How to use


The Model Chooser editor can be used to select the current 3D model. Select a 3D model in the list and then press Load model.


This tutorial uses an aggregated Model widget.

Use the standard GUI controls to manipulate the scene.

See Controls for details.
