Geometric tables - Polygon Tables
1) Vertex table: Keep vertices' coordinates values in the object.
2) Edge table: Keep pointers back in to the vertex table for identification of the vertices related to all polygon edges.
3) Polygon table or polygon surface table: Keep pointers back in the edge table for consideration of the edges associated to the polygon surface under construction.
This tabular representation of a polygon surface is demonstrated in Figure. Such representations assist one to rapidly refer to the data associated to a polygon surface. Also, while the data is put for processing then the processing can be fairly efficient, leading to efficient display of the object under identification.
