Dvojrozmrných

Dvojrozmrných is the non-diacritic variant often used in Czech texts to refer to the genitive plural form of dvojrozměrný, meaning two-dimensional. In standard Czech, the form is dvojrozměrných; in texts without diacritics it may appear as dvojrozmrných. It is a grammatical form rather than a separate concept, but it is frequently encountered in discussions about two-dimensional objects, spaces, or representations.

Two-dimensional, or 2D, describes something that has length and width but no perceivable depth. In geometry and mathematics, 2D space is the plane in which points are determined by two coordinates, typically x and y. It contrasts with three-dimensional space, which uses three coordinates (x, y, z). Many practical representations, such as maps, blueprints, and computer graphics, are modeled in two dimensions and then projected or mapped to a plane for viewing or analysis.

In applied contexts, dvojrozměrné concepts appear in various fields. In geometry and trigonometry, planar shapes, area, and transformations like translation, rotation, reflection, and scaling are studied within 2D space. In computer science, 2D refers to arrays or matrices with two indices (rows and columns) and to images and graphics produced in two dimensions, including raster (pixel-based) and vector formats. In cartography and engineering, 2D drawings and plans represent objects from a top-down or orthographic perspective.

Etymologically, dvojrozměrný combines dva (two) with rozměr (dimension) plusný (adjective suffix), yielding a term that describes entities with two dimensions. The form dvojrozměrných is encountered in grammatically inflected contexts.
