# Linear Perspective: 4

Linear Perspective - Linear perspective is a mathematical system for creating apparent depth and volume on a surface. Linear perspective has several aspects:
(1) forms diminish in scale as they recede into the distance;
(2) the point at which all forms completely disappear (are too small to see) is called a vanishing point;
(3) in basic linear perspective (one-point and two-point perspective), the vanishing points are positioned at eye level, referred to as the horizon line; and
(4) a fixed viewing point is required.

One-point perspective requires a single vanishing point on the horizon line to which all lines receding into space converge. If a cube is depicted, the viewer will face a flat plane of the cube. Two-point perspective requires two vanishing points on the horizon line. If a cube is depicted, the viewer will face an edge of the cube. Three-point perspective requires three vanishing points - usually two of the vanishing points are on the horizon line and a third is above or below the horizon line.
