In 3D computer graphics, hidden surface determination (also known as hidden surface removal (HSR), occlusion culling (OC) or visible surface determination (VSD)) is the process used to determine which surfaces and parts of surfaces are not visible from a certain viewpoint. 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. The process of hidden surface determination is sometimes called hiding, and such an algorithm is sometimes called a hider. The analogue for line rendering is hidden line removal. Hidden surface determination is necessary to render an image correctly, so that one cannot look through walls in virtual reality.

Famous quotes containing the words hidden and/or surface:
“Art for art’s sake? I should think so, and more so than ever at the present time. It is the one orderly product which our middling race has produced. It is the cry of a thousand sentinels, the echo from a thousand labyrinths, it is the lighthouse which cannot be hidden ... it is the best evidence we can have of our dignity.”
—E.M. (Edward Morgan)
“It was a pretty game, played on the smooth surface of the pond, a man against a loon.”
—Henry David Thoreau (1817–1862)
