Definition: The word 'contour' is an adjective used to describe a curved line or shape, particularly in geometry and engineering contexts. It refers to the characteristic line or path that forms the boundary of a body, especially one that extends beyond a specified location on the surface of the earth. In geometry, the term "contour" can be used to refer to two types of surfaces: the "internal" surface (or "surface of revolution") and the "external" surface (or "surface of rotation"). The internal surface is defined by a single line that does not extend beyond the boundaries of the body; the external surface is defined by a curved path or curve. In engineering, the term "contour" can be used to refer to the surface or boundary of an object in 3D space. For example, in computer graphics and modeling, it may refer to the surface of a model or the outer boundary of a scene. In architecture, the term is often used to describe the shape or outline of a building or structure. Overall, "contour" refers to the characteristic line that forms the boundaries of an object or system, especially one extending beyond a specified location on the surface of the earth.
