WebHidden lines and surfaces algorithms fall into 2 categories: 1. image-precision (device-precision) algorithms: work on a pixel basis by determining visibility at each pixel "sampling": samples object geometry … 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
