| − | '''Three-dimensional''', tri-dimensional or 3D is geometric mathematics describing generalized cube space. Euclidean space is a two-dimensional plane. Three-dimensional Euclidean plane is determined by three coordinates; X, Y, & Z or R<sub>n</sub> or n = 3. Common cube coordinates are measured by width, height, depth which is three planes. | + | '''Three-dimensional''', tri-dimensional or 3D in geometric mathematics is a generalized description of cubed space.<ref>"three-dimensional", '''Definition 2, et 4''',''The American Heritage® Dictionary of the English Language, 5th Edition''.
