Geon

A geon is a fundamental, three-dimensional shape that can be combined with other geons to form more complex objects. Think of them as the building blocks of physical forms—like cylinders, cones, or spheres—that can be easily recognized regardless of their orientation or position. In psychology, the concept helps explain how our brains identify objects by recognizing these basic shapes, even when they are partially hidden or viewed from different angles. Overall, geons simplify the understanding of shape recognition and the construction of complex forms from simple, recognizable components.
