three-dimensional

Three-dimensional refers to objects or space that have length, width, and height. These dimensions allow us to perceive depth and volume, so objects are not flat but occupy a position in the physical world. For example, a cube or a person has size in all three directions, enabling us to see and understand their form in real life. Unlike flat, two-dimensional images or drawings, three-dimensional objects can be viewed from different angles and possess measurable volume and spatial relationships within their environment.
