These visual rays are discrete, but we perceive a continuous image because our eyes, and thus our visual rays, move very quickly. [ 7 ]
Denote the three vertices of one triangle by a, b and c, and those of the other by A, B and C. Axial perspectivity means that lines ab and AB meet in a point, lines ac and AC meet in a second point, and lines bc and BC meet in a third point, and that these three points all lie on a common line called the axis of perspectivity.
