Quad buffering uses double buffering with a front buffer and back buffer for each eye, totaling four buffers Left front buffer Left back buffer Right front buffer Right back buffer Similarly to the v sync in 2D mode, quad buffering allows to swap the front and back buffers for both eyes in sync, allowing the display to seamless work with different rendering frame rates.

The Great Quadrangle , more popularly known as Tom Quad , is one of the quadrangles of Christ Church, Oxford , England . It is the largest college Quadrangle architecture quad in Oxford , measuring 264 by 261 feet. Although it was begun by Cardinal Wolsey , he was unable to complete it. Wolsey planned that it would actually be a cloister , and the supports required for this can be seen at short intervals around the quadrangle. The quad was finished when John Fell clergyman John Fell was Dean. The funds for the building of Tom Quad were found from the suppression of three Norbertine abbeys. It is dominated to the west by Tom Tower , designed by Sir Christopher Wren . On the east side is the entrance to Christ Church Cathedral, Oxford Christ Church Cathedral and at the south east corner is the entrance to the college dining hall . The north contains the homes of the Canon priest canons of Christ Church, and much of the east side is taken up with the Deanery , in which the Dean of the college lives. On the north east side, the quad leads, via Kilcannon, to Peckwater Quadrangle and the college library. In the north west part of the quad is the Junior Common Room JCR . Parts of the quad are still lived in by undergraduates, including the staircase above the Porter s lodge, known as Bachelors Row , to the left of the quadrangle when entered via Tom Gate. Bachelors Row is only inhabited by first year male undergraduates. In the centre of the quad, there is an ornamental pond with a statue of Mercury mythology Mercury . In the past, it was traditional for hearties sporty students to throw aesthetes more artistic students into this pond. Currently, entrance to Mercury carries a heavy fine for undergraduates.

A quad edge data structure is a computer representation of the topology of a dimension two dimensional or three dimensional CW complex map , that is, a graph theory graph drawn on a closed surface . Overview The quad edge data structure represents simultaneously both the map, its dual graph dual and mirror image. can represent the most general form of a map, admitting vertices and faces of degree 1 and 2. is a variant of the earlier winged edge data structure. The fundamental idea behind the quad edge structure is the recognition that a single edge, in a closed polygonal mesh topology, sits between exactly two faces and exactly two vertices. Thus, it can represent a dual of the graph simply by reversing the convention on what is a vertex and what is a face. Details The quad edge structure gets its name from the general mechanism by which they are stored. A single Edge structure conceptually stores references to up to two faces, two vertices, and 4 edges. The four edges stored are the edges starting with the two vertices that are attached to the two stored faces. Uses Much like winged edge Winged Edge , quad edge structures are used in programs to store the topology of a 2D or 3D polygonal mesh. The mesh itself does not need to be closed in order to form a valid quad edge structure. Using a quad edge structure, iterating through the topology is quite easy. Often, the interface to quad edge topologies is through directed edges. This allows the two vertices to have explicit names start and end , and this gives faces explicit names as well left and right, relative to a person standing on start and looking in the direction of end . The four edges are also given names, based on the vertices ... edge Doubly connected edge list References The quad edge data structure was described in the paper ... links http www.cs.cmu.edu afs andrew scs cs 15 463 2001 pub src a2 quadedge.html A quad edge implementation in C . http www.ic.unicamp.br stolfi EXPORT software c 2000 05 04 libquad A quad edge ... more details

Unreferenced date March 2007 Image Figure roller skates.jpg thumb right 200px Example of quad skate. The four wheeled turning roller skates roller skate , or quad skate , with four wheel s set in two side by side pairs, was first designed in 1863 in New York City by James Leonard Plimpton in an attempt to improve previous designs. The skate contained a pivoting action using a rubber cushion, and this allowed the skater to skate a curve just by leaning to one side. It was a huge success, so much so that the first public skating rink was opened in 1866 in Newport, Rhode Island with the support of Plimpton. The design of the quad skate allowed easier turns and maneuverability. The quad skate came to dominate the industry for more than a century. Arguably, the most important advance in the realistic use of roller skates as a pleasurable pastime took place in Birmingham, England in 1876 when William Bown patented a design for the wheels of roller skates. Bown s design embodied his effort to keep the two bearing surfaces of an axle , fixed and moving, apart. Bown worked closely with Joseph Henry Hughes , who drew up the patent for a ball or roller bearing race for bicycle and carriage wheels in 1877. Hughes patent included all the elements of an adjustable system. These two men are responsible for modern day roller skate and skateboard wheels, as well as the ball bearing race inclusion in velocipede s later to become motorbike s and automobile s. Another improvement came in 1876, when the toe stop was first patented. This provided skaters with the ability to stop promptly upon tipping the skate onto the toe.
