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 [citation needed]. The process of hidden-surface determination is sometimes called hiding, and such an algorithm is sometimes called a hider[citation needed]. WebHidden-line removal. In 3D computer graphics, solid objects are usually modeled by polyhedra. A face of a polyhedron is a planar polygon bounded by straight line segments, called edges. Curved surfaces are usually approximated by a polygon mesh. Computer programs for line drawings of opaque objects must be able to decide which edges or … WebJun 7, 2024 · Back face detection algorithmHidden surface elimination pale benedicto rizal

"WebAn interesting approach to the hidden-surface problem was developed by Warnock. He developed area subdivision algorithm which subdivides each area into four equal squares. At each stage in the recursive-subdivision process, the relationship between projection of each polygon and the area of interest is checked for four possible relationships: 1.
