3D

3D, or three-dimensional, refers to objects and spaces that have length, width, and height—meaning they occupy physical space in all directions. Unlike flat pictures or drawings that are two-dimensional and only show height and width, 3D objects have depth, making them appear more lifelike and tangible. This concept is used in technology such as 3D movies, video games, and modeling, allowing for more realistic visuals. Essentially, 3D provides a sense of volume and spatial relationships, enabling us to perceive and interact with objects more naturally as we do in the real world.
