    The most famous example is the Rapid Rectilinear Lens developed by John Henry Dallmeyer in 1866. It allowed distortionless photos to be taken quickly for the first time, and was a standard lens design for 60 years. [1]: 59 As of 2020, the Laowa 9mm f/5.6 lens is the world's widest rectilinear lens for full frame cameras.

    The Rapid Rectilinear also named Aplanat is a famous photographic lens design. The Rapid Rectilinear is a lens that is symmetrical about its aperture stop with four elements in two groups. It was introduced by John Henry Dallmeyer in 1866. The symmetry of the design greatly reduces radial distortion, improving on the Petzval lens. Aplanat ...

    Rectilinear prophecy, where a straight line can be drawn from the prophecy to the fulfillment without any branches as in the case of typological interpretations Near-rectilinear halo orbit , a highly-elliptical orbit around a Lagrangian point of a moon, that due to the moons orbital movement, will be nearly rectilinear in some frames of reference.

    The Globe's symmetric formula directly influenced the design of the Dallmeyer Rapid-Rectilinear (UK) and Steinheil Aplanat (modern Germany). By coincidence, John Dallmeyer 's Rapid-Rectilinear and Adolph Steinheil's Aplanat had virtually identical symmetric four-element formulae, arrived at almost simultaneously in 1866, all of which corrected ...

    Rectilinear Research Corporation was a manufacturer of loudspeakers. The company was formed around 1966 and its principal was Morris I. Wiener (alt. sp. "Weiner") of Plandome Manor, New York . [ 1 ] Arnold Schwartz, James Bongiorno, Marty Gersten, Jon Dahlquist, and Richard Shahinian were at different times and at different stages working with ...

    en.wikipedia.org/wiki/Rectilinear_polygon

    A rectilinear polygon is a polygon all of whose sides meet at right angles. Thus the interior angle at each vertex is either 90° or 270°. Rectilinear polygons are a special case of isothetic polygons. In many cases another definition is preferable: a rectilinear polygon is a polygon with sides parallel to the axes of Cartesian coordinates ...

    On a grander scale, Philadelphia was designed on a rectilinear street grid in 1682, one of the first cities in North America to use a grid system. [ 12 ] [ 13 ] At the urging of city founder William Penn , surveyor Thomas Holme designed a system of wide streets intersecting at right angles between the Schuylkill River to the west and the ...

    en.wikipedia.org/wiki/Steiner_tree_problem

    The rectilinear Steiner tree problem is a variant of the geometric Steiner tree problem in the plane, in which the Euclidean distance is replaced with the rectilinear distance. The problem arises in the physical design of electronic design automation.
