Wire frame

• A wireframe is a basic visual guide used in interface design to suggest the structure of an interface and relationships between its pages. Typically, wireframes are completed before any artwork is developed.
• A wire frame model is a visual presentation 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.
