Linear motion, also called rectilinear motion, [1] is one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension. The linear motion can be of two types: uniform linear motion , with constant velocity (zero acceleration ); and non-uniform linear motion , with variable velocity ...
English: Comparison of two stitched pictures File:Blinden Schule KW 31 Fotos Mercator.jpg and File:Blinden Schule KW 31 Fotos Rectilinear.jpg of the school for the blind in Königs Wusterhausen. The first image was created in Mercator projection, the second in rectilinear (perspective) projection.
While this example has been rectilinear-corrected by software, high quality wide-angle lenses are built with optical rectilinear correction. In photography, a rectilinear lens is a photographic lens that yields images where straight features, such as the edges of walls of buildings, appear with straight lines, as opposed to being curved.
The earliest zooms came out between 1929 and 1932 for professional motion picture cameras and were called "Traveling," "Vario" and "Varo" lenses. [ 1 ] : 155–156 The first zoom lens for still cameras was the Voigtländer-Zoomar 36-82mm f/2.8 (USA/West Germany) of 1959, [ 97 ] for Voigtländer Bessamatic series (1959, West Germany) 35mm leaf ...
Linear motion – motion that follows a straight linear path, and whose displacement is exactly the same as its trajectory. [Also known as rectilinear motion] Reciprocal motion; Brownian motion – the random movement of very small particles; Circular motion; Rotatory motion – a motion about a fixed point. (e.g. Ferris wheel).
Rectilinear polygon, a polygon whose edges meet at right angles; Rectilinear propagation, a property of waves; Rectilinear Research Corporation, a now defunct manufacturer of high-end loudspeakers; Rectilinear style, the third historical division of English Gothic architecture; Rectilinear motion or linear motion is motion along a straight line
Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
The Zeiss 8R Ultra Prime T2.8 is a rectilinear wide angle motion picture lens with an even slightly wider field of view, even when considering its smaller sized image circle. It is intended as an alternative to the Nikkor 8mm f/2.8 fisheye, which has seen frequent film and video use.
