geometry - Perspective projection of a sphere on a plane

WebSay I want to represent points of the complex plane in the sphere S 2 using stereographic projection. That is, the Riemann sphere: Given the coordinates ( x, y) of a point of the plane, see the point and its spherical image, and optionally, the line through the north pole and ( x, y, 0). Given a circle in the plane, (that is, its center ( x, y ... WebThis is a fundamental projection which can be envisioned by imagining placing a flat piece of paper tangent to a sphere and projecting a light out from its center. Obviously, only less than 180 degrees of longitude can be represented with this projection (exactly 180 degrees would require an image of infinite width), and in practice, far less. flugplan helvetic ab bern 2022 https://ezsportstravel.com
