The PolygonGroup is a group of polygons with a MovingTransform3D. PolygonGroups can also contain other PolygonGroups.

Constructor Summary

PolygonGroup()
Creates a new, empty PolygonGroup.

PolygonGroup(java.lang.String name)
Creates a new, empty PolygonGroup with te specified name.

See Also:

hasNext(), nextPolygon()

hasNext

public boolean hasNext()

Checks if there is another polygon in the current iteration.

See Also:

resetIterator(), nextPolygon()

isEmpty

public boolean isEmpty()
