Stereographic projection


Also found in: Encyclopedia, Wikipedia.
(Geom.) a method of representing the sphere in which the center of projection is taken in the surface of the sphere, and the plane upon which the projection is made is at right andles to the diameter passing through the center of projection.

In the first three episodes of the film, the notion of stereographic projection and mapping of the world is established, then a transition from the view of a 2-D world to a 3-D and gradually building of a view of 4-D via stereographic projection and coloring of hyper-faces is achieved.
A planisphere works using stereographic projection.
Thus, the stereographic projection (16,30), of each unit vector representing the body segments was calculated by centering an imaginary unit sphere proximally at each of the segments.

Most varieties have the same basics: a sighting device, a movable star map in the form of a metal network including a finely scaled zodiac ring; a flat, stereographic projection of the sky's altazimuth coordinate grid from horizon to zenith; and a finely divided circular scale of hours around the outside.

Dennis first came to our attention when in 2011, aged only 18, he submitted an excellent report on the Western Elongation of Venus of that year to the Mercury and Venus Section, showing the development of clouds in the UV and including cylindrical and stereographic projection maps made from his images, which were of a high quality, taken with a 235mm (9.
computer-aided design techniques, and much more - in-depth appendices go the extra mile to explain spherical trigonometry and stereographic projection.
Stereographic projection is the projection onto a plane tangent to the zenith, where the center of the projection is the nadir (that is, the point diametrically opposite the zenith).
