is specified by two tables: (1) Vertex Table, and, (2) Edge Table. The vertex table consists of three-dimensional coordinate values for each vertex with reference to the origin. Edge table specifies the start and end vertices for each edge. A naive interpretation could create a wire-frame representation by simply drawing straight lines between the screen coordinates of the appropriate vertices using the edge list. Unlike representations designed for more detailed rendering, face information is not specified (it must be calculated if required for solid rendering). Appropriate calculations have to be performed to transform the 3D coordinates of the vertices into 2D screen coordinates.
