What is projective geometry?
Projective geometry is a branch of mathematics that studies the properties of geometric figures that are invariant under projective transformations. A projective transformation is a mapping that preserves straight lines and incidence relations, but not necessarily distances, angles, parallelism or similarity. For example, a perspective projection is a projective transformation that maps points on a three-dimensional scene onto a two-dimensional plane, such as a camera or a painting.
Projective geometry can be seen as a generalization of Euclidean geometry, which is based on the assumption that parallel lines never meet. In projective geometry, parallel lines are considered to meet at a point at infinity, which is added to the ordinary plane to form the projective plane. Similarly, other dimensions can be extended by adding points, lines or planes at infinity to form projective spaces. Projective geometry can also be seen as a simplification of Euclidean geometry, as it ignores some measurements and focuses on more essential properties of geometric figures.
What are some applications of projective geometry?
Projective geometry has many applications in various fields of science, art and engineering, such as:
Perspective drawing: Projective geometry provides the rules and methods for creating realistic drawings of three-dimensional objects on a two-dimensional surface, using techniques such as vanishing points, horizon lines and foreshortening.
Computer vision: Projective geometry helps to analyze and manipulate images captured by cameras or other sensors, such as stereo vision, camera calibration, shape from motion, image stitching and 3D reconstruction.
Computational geometry: Projective geometry offers some tools and algorithms for solving problems involving geometric objects and their relations, such as convex hulls, Voronoi diagrams, Delaunay triangulations and duality.
Algebraic geometry: Projective geometry provides a framework for studying algebraic curves and surfaces, which are defined by polynomial equations. Projective geometry also helps to classify and compare different types of curves and surfaces.
