Ruumipunktis

Ruumipunktis is a term used in Finnish-language technical writing to denote a point located within a defined spatial frame, typically a room coordinate system. It refers to a precise position specified by three coordinates in three-dimensional space, and it may be accompanied by metadata such as a point identifier or a room reference.

In practice, a ruumipunktis serves as the fundamental unit for marking locations inside a building or interior space. It is commonly used in fields such as building information modelling (BIM), computer-aided design (CAD), interior design, and game development. The local frame is usually defined by the room boundary and a chosen reference direction, which allows consistent placement of objects, fixtures, or routing points across multiple spaces and projects.

Coordinate relationships are expressed by transforming ruumipunktis between local room coordinates and a global site or model coordinate system. Typical transformations include translation (shifting), rotation, and, in some workflows, scaling. These operations enable alignment of room-level points with architectural drawings, sensor layouts, or virtual environments.

Data representation for a ruumipunktis commonly includes fields such as room_id, x, y, z, and optional attributes like point_id, label, timestamp, and reliability. The concept supports precise localisation tasks, collision detection, and spatial analyses within complex architectural models. Etymologically, the term combines elements related to space or room and a notion of a point, reflecting its role as a spatial reference within a room.
