This video shows a 3D sandbox topographic simulation (often called an augmented reality sandbox). It uses colored elevation mapping projected onto sand to simulate real-world landforms and tectonic features such as mountains, valleys, ridges, and basins. The colors represent different elevations — blue for lowlands, green for plains, brown for highlands, and white for peaks. It’s often used to demonstrate plate interactions, erosion, or sedimentation processes in real time. Follow @geology forum
