Linear Perspective


One-Point

One-point perspective is used when one face of the represented object is parallel to the front of the picture plane. Receding horizontals called "orthogonals" converge to a single vanishing point that falls on a horizon line. Together, the horizon line and vanishing point determine the exact position of the viewer's line of sight in relation to the rendered space. A single vanishing point may be shared by some or all of the objects in the composition. In some images, a single, centrally positioned vanishing point is shared by all objects in the composition. We typically see interiors drawn using this method.
