Pisteobjekti

Pisteobjekti, or point object, is a basic geometric primitive representing a single location in a coordinate system. It is used in mathematics, computer graphics, CAD, and GIS to denote an exact position without any extent.

In two dimensions, a pisteobjekti is defined by coordinates (x, y); in three dimensions it has (x, y, z). A point has no length, width, height, or area. It may carry optional metadata such as an identifier, label, or attributes, and may be stored in a variety of data structures (class, struct, or record) depending on the language or framework. In GIS and CAD applications, a point can be part of a point feature or a vertex in a geometry.

Common operations on a pisteobjekti include measuring the distance to another point, translating or moving the point by a vector, and applying affine transformations. Points are often treated as vectors from the origin in mathematical contexts. In software libraries, a point object can be immutable or mutable and may provide methods for cloning, comparing, or converting to other representations (array, string, or JSON).

In usage, pisteobjekti serve as reference marks, control points in design, markers on maps, or vertices in polylines or polygons. They are foundational in graphics pipelines, spatial analysis, and geometric modeling because they provide a precise location without additional geometry.
