Project sphere onto plane

WebJul 21, 2024 · This requires a projection from the curved space to the Euclidean plane. Take one of the earliest and simplest projections possible: the ‘plate careé’ projection. Nearly 2000 years old, this projection can map the sphere onto a flat plane in a simple way, and produces a reasonable-looking result. WebJun 30, 2024 · If you want a parameterisation of the projection, find a parameterisation of the surface, and a formula for the projection, and compose them. – Add a comment 2 Answers Sorted by: 4 If your surface is represented as S = S ( u, v) given a direction n → the projection is given as S n → ( u, v) = S ( u, v) − S ( u, v), n → n → n → 2

WebA map of the Riemann sphere onto itself is conformal if and only if it is a Möbius transformation. ... For example, stereographic projection of a sphere onto the plane augmented with a point at infinity is a conformal map. One can also define a conformal structure on a smooth manifold, as a class of conformally equivalent Riemannian metrics.
