A wire frame model is a visual presentation of an electronic representation of a three dimensional or physical object used in 3D computer graphics. 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. Dimension (from Latin measured out) is, in essence, the number of degrees of freedom available for movement in a space. ... The rewrite of this article is being devised at Talk:3D computer graphics/Temp. ... In geometry, a vertex (Latin: whirl, whirlpool; plural vertices) is a corner of a polygon (where two sides meet) or of a polyhedron (where three or more faces and an equal number of edges meet). ...
Using a wire frame model allows visualization of the underlying design structure of a 3D model. Traditional 2-dimensional views and drawings can be created by appropriate rotation of the object and selection of hidden line removal via cutting planes. Sample image of a wireframe rendering of a cube, icosahedron, and sphere. ... Three dimensions A cube (or hexahedron) is a Platonic solid composed of six square faces, with three meeting at each vertex. ... An icosahedron [ËŒaıkÉ™sÉ™hiËdrÉ™n] noun (plural: -drons, -dra [-drÉ™]) is a polyhedron having 20 faces. ... A sphere is a perfectly symmetrical geometrical object. ... 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). 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. Wikipedia does not have an article with this exact name. ... Rendering is the process of generating an image from a model, by means of a software program. ...
The wire frame format is also well suited and widely used in programming tool paths for DNC (Direct Numerical Control) machine tools.
