polylinja

A polylinja, also known as a polyline, is a geometric figure consisting of multiple connected line segments. Unlike a single straight line, a polylinja may have several bends and angles, forming a continuous path defined by a sequence of points called vertices. These vertices are connected in order, creating a piecewise linear curve that can be open or closed.

Polylinjas are commonly used in computer graphics, geographic information systems (GIS), and computer-aided design (CAD) applications. They serve as fundamental elements for representing roads, rivers, boundaries, and other linear features in digital maps. In vector graphics, polylinjas are utilized to create complex shapes and outlines, allowing for flexible editing and manipulation.

The mathematical representation of a polylinja involves a list of coordinate pairs, each corresponding to a vertex. When the first and last vertices are the same, the polylinja forms a polygon, which can be filled or outlined depending on the application.

In terms of properties, polylinjas can vary significantly in complexity and length. They are defined primarily by their vertices and the sequence in which these points are connected. The accuracy and detail of a polylinja depend on the number and placement of its vertices.

In summary, a polylinja is a versatile and fundamental shape used across various disciplines to model linear and polygonal features efficiently. Its simplicity and adaptability make it essential in digital geometry and spatial analysis.
