A wire frame model is a visual presentation of an electronic representation of a three dimensional or physical object used in 3D computer graphics. In mathematics the dimension of a Space is roughly defined as the minimum number of Coordinates needed to specify every point within it 3D computer graphics (in contrast to 2D computer graphics) are graphics that use a three-dimensional representation of geometric data that is stored in the computer It is created by specifying each edge of the physical object where two mathematically continuous smooth surfaces meet, or by connecting an object's constituent vertices using straight lines or curves. The object is projected onto the computer screen by drawing lines at the location of each edge.

Using a wire frame model allows visualization of the underlying design structure of a 3D model. A cube is a three-dimensional solid object bounded by six square faces facets or sides with three meeting at each vertex. In Geometry, an icosahedron ( Greek: eikosaedron, from eikosi twenty + hedron seat /ˌaɪ "Globose" redirects here See also Globose nucleus. A sphere (from Greek σφαίρα - sphaira, "globe Traditional 2-dimensional views and drawings can be created by appropriate rotation of the object and selection of hidden line removal via cutting planes. Hidden line removal is an extension of wireframe rendering where lines (or segments of lines covered by surfaces are not drawn

Since wireframe renderings are relatively simple and fast to calculate, they are often used in cases where a high screen frame rate is needed (for instance, when working with a particularly complex 3D model, or in real-time systems that model exterior phenomena). In Computer science, real-time computing (RTC is the study of hardware and software systems that are subject to a "real-time constraint"—i When greater graphical detail is desired, surface textures can be added automatically after completion of the initial rendering of the wireframe. This allows the designer to quickly review changes or rotate the object to new desired views without long delays associated with more realistic rendering. Rendering is the process of generating an image from a model, by means of computer programs

The wire frame format is also well suited and widely used in programming tool paths for DNC (Direct Numerical Control) machine tools.
