Information about Wire Frame Model
This article is about the 3D visualization. For the web design technique, see Website wireframe.
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.

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

wireframes are a basic visual guide used to suggest the layout and placement of fundamental design elements in the interface design. Because of this they must be completed before any artwork is developed.

Hidden line removal is an extension of wireframe rendering where lines (or segments of lines) covered by surfaces are not drawn.
This is not the same as hidden face removal since this involves depth and occlusion while the other involves normals.

Rendering is the process of generating an image from a model, by means of computer programs. The model is a description of three dimensional objects in a strictly defined language or data structure. It would contain geometry, viewpoint, texture, lighting, and shading information.

Animation is the rapid display of a sequence of images of 2-D artwork or model positions in order to create an illusion of movement. It is an optical illusion of motion due to the phenomenon of persistence of vision, and can be created and demonstrated in a number of ways.
