To load all objects in this example consult the polygons.loader utility
|
||
|
|
file (note that the *.loader files are Prolog files).
|
||
|
|
|
||
|
|
You will need to load the objects in the roots and relations
|
||
|
|
examples (consulting the corresponding roots.loader and relations.loader
|
||
|
|
files).
|
||
|
|
|
||
|
|
You will also need to consult the following files in the library directory:
|
||
|
|
events.loader, types.loader, metapredicates.loader, and hierarchies.loader.
|
||
|
|
|
||
|
|
In this example we have several types of polygons that can be concentric.
|
||
|
|
This is represented by a concentric binary relation ensuring that whenever
|
||
|
|
a polygon is moved towards a new position, all polygons likewise concentric
|
||
|
|
are moved along with them.
