A hidden-surface determination algorithm is a solution to the visibility problem, which was one of the first major problems in the field of 3D computer graphics.[citation needed] The process of hidden-surface determination is sometimes called hiding, and such an algorithm is sometimes called a hider.[citation needed] When referring to line rendering it is known as hidden-line removal.[citation needed] Hidden-surface
