edgePoints

protected final GeoPoint[] edgePoints

These are the edge points of the shape, which are defined to be at least one point on each surface area boundary. In the case of a solid, this includes points which represent the intersection of XYZ bounding planes and the planet, as well as points representing the intersection of single bounding planes with the planet itself.

Constructor Detail

StandardXYZSolid

public StandardXYZSolid(PlanetModel planetModel,
                double minX,
                double maxX,
                double minY,
                double maxY,
                double minZ,
                double maxZ)

Sole constructor

Parameters:

planetModel - is the planet model.

minX - is the minimum X value.

maxX - is the maximum X value.

minY - is the minimum Y value.

maxY - is the maximum Y value.

minZ - is the minimum Z value.

maxZ - is the maximum Z value.

Method Detail

getEdgePoints

protected GeoPoint[] getEdgePoints()

Description copied from class: BaseXYZSolid

Get the edge points for this shape.

Specified by:

getEdgePoints in class BaseXYZSolid

Returns:

the edge points.

isWithin

public boolean isWithin(double x,
               double y,
               double z)

Description copied from interface: Membership

Check if a point is within this shape.

Specified by:

isWithin in interface Membership

Specified by:

isWithin in class BaseXYZSolid

Parameters:

x - is x coordinate of point to check.

y - is y coordinate of point to check.

z - is z coordinate of point to check.

Returns:

true if the point is within this shape

getRelationship

public int getRelationship(GeoShape path)

Description copied from interface: GeoArea

Find the spatial relationship between a shape and the current geo area. Note: return value is how the GeoShape relates to the GeoArea, not the other way around. For example, if this GeoArea is entirely within the shape, then CONTAINS should be returned. If the shape is entirely enclosed by this GeoArea, then WITHIN should be returned. It is permissible to return OVERLAPS instead of WITHIN if the shape intersects with the area at even a single point. So, a circle inscribed in a rectangle could return either OVERLAPS or WITHIN, depending on implementation. It is not permissible to return CONTAINS or DISJOINT in this circumstance, however. Similarly, it is permissible to return OVERLAPS instead of CONTAINS under conditions where the shape consists of multiple independent overlapping subshapes, and the area overlaps one of the subshapes. It is not permissible to return WITHIN or DISJOINT in this circumstance, however.

Parameters:

path - is the shape to consider.

Returns:

the relationship, from the perspective of the shape.

equals

public boolean equals(Object o)

Overrides:

equals in class BaseXYZSolid

hashCode

public int hashCode()

Overrides:

hashCode in class BaseXYZSolid

toString

public String toString()
