WebThe identification and removal of these surfaces is called Hidden-surface problem. In this paper I review some visible surface detection algorithms like Z buffer method, Area subdivision method, Scan line method etc. Keywords— Visible surface detection algorithms, Z buffer, Area subdivision, Scan line method etc. WebA 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.

WebSep 28, 2015 · Scan-Line Method. It is an extension to the scan line filling. In this method, as each scan line is processed, all polygon surfaces intersecting that line are examined to determine which are visible. Across each scan line, depth calculations are made for each overlapping surface to determine which is nearest to the view plane.
