Tasopiirroksen

Tasopiirroksen is a Finnish term that literally means plan or planar drawing. It is not a fixed, universally used concept, and its definition varies by field. In general, it denotes a two-dimensional representation produced by projecting a three-dimensional object onto a plane, or a drawing prepared on a plane.

In architecture and technical drawing, tasopiirros often refers to a plan view (pohjapiirros) showing the layout from above. Such drawings are typically to scale and include dimensions, a north arrow, and standardized symbols for walls, doors, windows, and furniture. They serve as a blueprint for construction, planning, and spatial understanding.

In mathematics and computer graphics, tasopiirroksen can refer to a planar projection: a method of mapping three-dimensional coordinates to a two-dimensional plane. This can be an orthographic projection, where depth is suppressed, or a perspective projection, where depth cues are preserved but may include vanishing points. The term emphasizes the planar aspect of the resulting image rather than the projection method.

In art and design contexts, tasopiirroksen may denote any two-dimensional representation of a three-dimensional form drawn on a plane, focusing on layout and proportions rather than shading or perspective.
