The hidden-line algorithm uses n 2 exclusive read, exclusive write (EREW) PRAM processors. The EREW model is the PRAM variant closest to real machines. The hidden-line algorithm does O(n 2 log n) work, which is the upper bound for the best sequential algorithms used in practice. Cook, Dwork and Reischuk gave an Ω(log n) lower bound for finding ...
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.
In mathematics, a hidden line is a geometric edge line [1] that is not visible from an observer's view of a shape or object. Cubes with hidden lines: dotted, dashed, and thin lines. Cubes with no hidden lines, and a cube with dotted lines to give 3 dimensional reference

In wire-frame rendering, back-face culling can be used to partially address the problem of hidden-line removal, but only for closed convex geometry. A related technique is clipping, which determines whether polygons are within the camera's field of view at all.
