Piiripunkte

Piiripunkte is a Finnish term used to describe points that define or contribute to drawing, plotting, or shaping geometric forms in graphical contexts. The concept is common in Finnish-language tutorials and software documentation and refers to coordinates that specify a shape, curve, or path. In vector graphics and computer-aided design, piiripunkteet are the vertices of polygons or the anchor points of curves, while control points influence the tangents of Bezier segments.

In Bezier and other curve representations, piiripisteet can be thought of as the main points that define the path, with additional control points shaping how the curve flows between them. In font design and outline modeling, piiripisteet determine the silhouettes of glyphs or surfaces. The term is therefore used across applications to discuss how a complex figure is constructed from discrete points.

In mathematics and numerical methods, piiripisteet also denote sample points on a curve or surface used for approximation, interpolation, or discretization. For example, a circle can be approximated by a polygon whose vertices are piiripisteet located on the circumference, enabling simple computation and rendering.

In data visualization and geographic information systems, piiripisteet are the plotted coordinates that represent observations or features. They are typically stored as coordinate pairs (x, y) or (longitude, latitude) and may be connected to form lines, polygons, or other geometric objects on a map or chart.

Overall, piiripunkte describe the fundamental building blocks—discrete points—that define larger geometric or graphical constructs across disciplines.
