Katselusuunnista

Katselusuunnista is Finnish for “viewing directions” or “lines of sight” and refers to the set of directions from which an object, scene, or space can be viewed. The term is formed from katselu (viewing) and suunnista (from suunnasta, directions) in the genitive plural form. It is used in Finnish-language discussions to describe orientation-related aspects of observation, visibility, or gaze.

In practice, katselusuunnista may denote the collection of directions considered in an analysis of visibility or perception. It appears in architecture and urban planning when evaluating sightlines from a building, street, or public space to a point of interest. In film and media studies, it can refer to the possible camera positions or angles that shape interpretation of a scene. In computer graphics, gaming, and vision research, katselusuunnista describes the set of viewing directions used to render scenes, simulate gaze patterns, or analyze visibility.

Typical methods involve describing directions with angular coordinates, such as azimuth and elevation, relative to a reference frame like true north and horizontal plane. The concept is often linked to related ideas such as viewing angle (katselukulma), field of view, and viewing geometry. Practically, specifying a subset of katselusuunnista can optimize design decisions, surveillance coverage, or visual storytelling.
