Examples of GPC Operations On Sets of Polygons
The following four images show examples of GPC computing operations between two polygon sets. The first polygon set comprises outlines of the United Kingdom and Ireland. The second polygon set comprises the four large inward-pointing arrows. In each example, the areas resulting from the GPC operation between the two sets of polygons are rendered in colour.
This example shows difference between the two sets:
This example shows intersection between the two sets:
This example shows union between the two sets:
This example shows exclusive-or between the two sets:

—Henry David Thoreau (1817–1862)
“Eddie did not die. He is no longer on Channel 4, and our sets are tuned to Channel 4; he’s on Channel 7, but he’s still broadcasting. Physical incarnation is highly overrated; it is one corner of universal possibility.”
