2DProjektion
2DProjektion is a general term for the process of mapping points from a higher‑dimensional space to a two‑dimensional plane. It is used in mathematics, computer graphics, engineering, and cartography to produce a two‑dimensional representation of a three‑dimensional scene or of higher‑dimensional data.
There are two principal classes of 2D projections. Orthographic (parallel) projection uses rays that are parallel
Perspective (central) projection uses rays emanating from a single viewpoint. Objects farther from the viewpoint appear
Mathematically, a projection can be described by a projection operator or a projection matrix, often using
Applications of 2D projections include rendering three‑dimensional scenes on screens, producing technical drawings, and projecting geographic
