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 - when outline of an object is to be displayed - similar to clipping a line segment against a window - most surface algorithms can be applied for hidden line …
The hidden-line algorithm uses n2 exclusive read, exclusive write (EREW) PRAM processors. The EREW model is the PRAM variant closest to real machines. The hidden-line algorithm does O ( n2 log n) work, which is the upper bound for the best sequential algorithms used in practice. Ver mais 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 Ver mais Hidden-line algorithms published before 1984 divide edges into line segments by the intersection points of their images, and then test each … Ver mais • Back-face culling Ver mais In 1988 Devai proposed an O(log n)-time parallel algorithm using n processors for the hidden-line problem under the concurrent read, exclusive write (CREW) parallel random … Ver mais • Patrick-Gilles Maillot's thesis, an extension of the Bresenham line-drawing algorithm to perform 3D hidden-lines removal; also … Ver mais Web1 de jan. de 1984 · An algorithm is described to generate pictures in arbitrary perspective from serially sectioned biological material.

Web20 de out. de 2006 · In order to remove these lines, hidden line algorithms are applied in the surface rendering software to create a wireframe which contains only visible lines and hides the lines covered by the surface. An algorithm which is often used is the one developed by Arthur Appel at IBM in the late 1960’s. “This ... Web1 de jan. de 1985 · A very simple, linear-running-time algorithm is presented for solving the hidden-line problem for star-shaped polygons. The algorithm first decomposes the visibility regions into edge-visible polygons and then solves the hidden-line problem for these simpler polygons. In addition to simplicity the algorithm possesses the virtue of affording …
