Stereographic projection is a method of mapping points from a sphere onto a plane. It works by projecting points from the surface of the sphere through a specific point, usually the "north pole," onto a flat surface, like a piece of paper. This technique preserves angles, making it useful in fields like cartography and computer graphics. This projection creates a circular map where the entire sphere is represented, but it distorts areas, especially near the edges. Despite this distortion, it provides a way to visualize three-dimensional objects in two dimensions, aiding in the study of geometry and topology.
