WebStereographic Projection Geographers have devised all sorts of projections from the curved surface of a sphere in three-space to flat two-dimensional maps. We have already been studying one of the most useful mapping techniques, central projection from a viewing point to a horizontal plane. The stereographic projection gives a way to represent a sphere by a plane. The metric induced by the inverse stereographic projection from the plane to the sphere defines a geodesic distance between points in the plane equal to the spherical distance between the spherical points they represent. See more In mathematics, a stereographic projection is a perspective projection of the sphere, through a specific point on the sphere (the pole or center of projection), onto a plane (the projection plane) perpendicular to the diameter through … See more The first stereographic projection defined in the preceding section sends the "south pole" (0, 0, −1) of the unit sphere to (0, 0), the equator to the See more Stereographic projection plots can be carried out by a computer using the explicit formulas given above. However, for graphing by hand these formulas are unwieldy. Instead, it … See more Cartography The fundamental problem of cartography is that no map from the sphere to the plane can accurately represent both angles and areas. In general, area-preserving map projections are preferred for See more The stereographic projection was known to Hipparchus, Ptolemy and probably earlier to the Egyptians. It was originally known as the planisphere … See more First formulation The unit sphere S in three-dimensional space R is the set of points (x, y, z) such that x + y + z = 1. Let N = (0, 0, 1) be the "north pole", and let … See more Complex analysis Although any stereographic projection misses one point on the sphere (the projection point), the … See more

WebSphere Projection Technology Sphere Projection Pandoras Box warping technology as a toolkit offers various spherical mapping techniques for various applications. With the 3D environment Pandoras Box breaks all limits of traditional content playback systems. WebSphere mapping 是基于这样一个事实:将一个理想高反射的球体置于场景中央,从一个角度无穷远处拍摄此球体,将得到一张全景图。 例如: 当然说是全景图,但是在球体背对拍摄方向的场景是看不到的,所以这个全景图是言过其实的,但是的实际效果上是不错的。 faraway puzzle escape level 4 walkthrough
