Simple Example of Wireframe Model
An object is specified by two tables: the vertex table and the edge table. The vertex table consists of three-dimensional coordinate values for each vertex with reference to the origin, while the edge table specifies the start and end vertices for each edge. After the appropriate calculations have been performed to transform the 3D coordinates of the vertices into 2D screen coordinates, a naïve interpretation could create a wireframe 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).
| Vertex | X | Y | Z |
|---|---|---|---|
| 1 | 1 | 1 | 1 |
| 2 | 1 | -1 | 1 |
| 3 | -1 | -1 | 1 |
| 4 | -1 | 1 | 1 |
| 5 | 1 | 1 | -1 |
| 6 | 1 | -1 | -1 |
| 7 | -1 | -1 | -1 |
| 8 | -1 | 1 | -1 |
| Edge | Start Vertex | End Vertex |
|---|---|---|
| 1 | 1 | 2 |
| 2 | 2 | 3 |
| 3 | 3 | 4 |
| 4 | 4 | 1 |
| 5 | 5 | 6 |

| 7 | 7 | 8 |
| 8 | 8 | 5 |
| 9 | 1 | 5 |
| 10 | 2 | 6 |
| 11 | 3 | 7 |

Famous quotes containing the words simple and/or model:
“Chaucer sawed life in half and out tumbled hundreds of unpremeditated lives, because he didn’t have the cast-iron grid of a priori coherence that makes reading Goethe, Shakespeare, or Dante an exercise in searching for signs of life among the conventions, compulsions, self-justifications, proofs, wise saws, simple but powerful messages, and poetry.”
—Marvin Mudrick (1921–1986)
“I’d like to be the first model who becomes a woman.”
—Lauren Hutton (b. 1944)
