Method Summary

AxisAlignedBoundingBoxXZ	getAxisAlignedBoundingBoxXZ()
PolygonXYZ	getOutlinePolygon() returns a counterclockwise polygon defining the object's ground footprint.
SimplePolygonXZ	getOutlinePolygonXZ() returns a counterclockwise polygon defining the object's ground footprint, projected onto the XZ plane.
MapElement	getPrimaryMapElement() returns the "primary" MapElement for this WorldObject; i.e.
protected Collection<TriangleXYZ>	getTriangulation() decompose this area into counterclockwise triangles

Method Detail

getOutlinePolygonXZ

public SimplePolygonXZ getOutlinePolygonXZ()

Description copied from interface: WorldObjectWithOutline

returns a counterclockwise polygon defining the object's ground footprint, projected onto the XZ plane.

Specified by:

getOutlinePolygonXZ in interface WorldObjectWithOutline

Returns:

outline polygon; null if this world object doesn't cover any area

getOutlinePolygon

public PolygonXYZ getOutlinePolygon()

Description copied from interface: WorldObjectWithOutline

returns a counterclockwise polygon defining the object's ground footprint.

Specified by:

getOutlinePolygon in interface WorldObjectWithOutline

Returns:

outline polygon; null if this world object doesn't cover any area

getAxisAlignedBoundingBoxXZ

public AxisAlignedBoundingBoxXZ getAxisAlignedBoundingBoxXZ()

Specified by:

getAxisAlignedBoundingBoxXZ in interface IntersectionTestObject

getPrimaryMapElement

public MapElement getPrimaryMapElement()

Description copied from interface: WorldObject

returns the "primary" MapElement for this WorldObject; i.e. the one it is most strongly associated with. Can be null if there is no (clear) primary element for this feature.

Specified by:

getPrimaryMapElement in interface WorldObject

getTriangulation

protected Collection<TriangleXYZ> getTriangulation()

decompose this area into counterclockwise triangles
