LINEAR PERSPECTIVE A system of rendering the appearance of three dimensions on a two-dimensional plane by making objects appear smaller as they recede and by making parallel lines converge in the distance at a vanishing point on a horizon line.
VANISHING POINT Where converging lines drawn in linear perspective seem to disappear into a distant dot on the horizon line.
ORTHOGONAL LINES Lines or edges in a picture that lead the viewer’s eyes to the vanishing points in an illusional three-dimensional space.
ATMOSPHERIC (AERIAL) PERSPECTIVE The technique of representing dimensional space by making objects close to the viewer appear crisp and vibrant and making them fuzzy and less intense in color and tone as thet recede.
ISOMETRIC PERSPECTIVE A means of rendering three-dimensional objects without reliance on vanishing points or converging lines; scale of objects remains the same regardless of the distance from the foreground and background.
