Polygon Tables - curves and surfaces
All polygons are analogous to a graph G (V, E). Remember that the analogy in which a polygon surface can be specified along with as a set of vertex coordinates and related attribute parameters such attributes may be colour, contrast and shading. Most systems utilize tables to store the information entered for all polygon and it's the data in these tables utilized for subsequent processing, manipulation and display of the objects in the scene. Since the data required being stored for an object in the scene engages both the geometric information and attributes related with the object.
The transformation regarding to the mirror reflection to this line L comprises the subsequent basic transformations: 1) Translate the intersection point A(0,c) to the origin, it
