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.
Advantages of Scan line Algorithm: This time and always we are working along with one-dimensional array as: x[0...x_max] for color not a 2D-array like in Z-buffer algorithm.
