Cylinder AR Interactive Demonstration

① This example uses GeoGebra's Augmented Reality (AR) feature to vividly display the 3D structure of a cylinder, allowing users to rotate the view to observe its base, lateral surface, and height. ② Core mathematical concepts involve solid geometry: the definition of a cylinder, how base radius and height affect volume and surface area, and 3D coordinate positioning. ③ Construction highlights: The Cylinder command is used with radius and height as primary parameters, linked to variables a, c, d, b (possibly controlling position or size) to create a dynamically adjustable cylinder model. ④ Suitable for upper secondary or early university students, this serves as an introduction to solid geometry, spatial reasoning training, and a demonstration of AR-assisted mathematical visualization.
