+title: AABB
+brief: This example demonstrates how to use the `model.get_aabb()` function in a 3D scene.
+scripts: aabb.script
+author: Artsiom Trubchyk
+---
+
+This example shows how to work with Axis-Aligned Bounding Boxes (AABB) in a 3D scene. The setup consists of falling cubes that are dynamically tracked by a camera using their combined bounding box. The example demonstrates:
+
+* How to create and manage a dynamic bounding box that updates with moving objects
+* Using `model.get_aabb()` to get object bounds
+* Camera positioning based on bounding box size
+* Dynamic object spawning with factory
+* Smooth camera transitions
+
+Press SPACE or click to spawn new cubes. The camera will automatically adjust to keep all objects in view based on their combined bounding box.
+
+The models used in this example are from Kenney's [Prototype Kit](https://kenney.nl/assets/prototype-kit), licensed under CC0.
