Method Details

point

public double[] point(double[] dst,
 double fx,
 double fz)

Gets the coordinates of a point in this bounding box.

The relative coordinates are both given in range [0-1]. Providing relative coordinates outside of this range will produce unexpected results.

Parameters:

dst - the double[] to attempt to store the point in

fx - the relative position of the point along the X axis

fz - the relative position of the point along the Z axis

Returns:

a double[] which contains the point (possibly the same as dst)

axisAlign

public Bounds2d axisAlign()
                   throws OutOfProjectionBoundsException

Returns:

a Bounds2d which contains the entire area enclosed by this bounding box

Throws:

OutOfProjectionBoundsException

toGeo

public CornerBoundingBox2d toGeo()
                          throws OutOfProjectionBoundsException

Returns:

this bounding box, projected to geographic coordinates

Throws:

OutOfProjectionBoundsException

fromGeo

public CornerBoundingBox2d fromGeo()
                            throws OutOfProjectionBoundsException

Returns:

this bounding box, projected to local coordinates

Throws:

OutOfProjectionBoundsException

toGeo

public CornerBoundingBox2d toGeo(@NonNull
 @NonNull GeographicProjection proj)
                          throws OutOfProjectionBoundsException

Returns:

this bounding box, projected to geographic coordinates using the given GeographicProjection

Throws:

OutOfProjectionBoundsException

fromGeo

public CornerBoundingBox2d fromGeo(@NonNull
 @NonNull GeographicProjection proj)
                            throws OutOfProjectionBoundsException

Returns:

this bounding box, projected to local coordinates using the given GeographicProjection

Throws:

OutOfProjectionBoundsException

validate

public CornerBoundingBox2d validate()
                             throws OutOfProjectionBoundsException

Ensures that this bounding box is entirely within valid projection bounds.

Throws:

OutOfProjectionBoundsException - if any part of this bounding box is out of valid projection bounds

minX

public double minX()

Specified by:

minX in interface Bounds2d

Returns:

the minimum X coordinate

maxX

public double maxX()

Specified by:

maxX in interface Bounds2d

Returns:

the maximum X coordinate

minZ

public double minZ()

Specified by:

minZ in interface Bounds2d

Returns:

the minimum Z coordinate

maxZ

public double maxZ()

Specified by:

maxZ in interface Bounds2d

Returns:

the maximum Z coordinate

toString

public String toString()

Overrides:

toString in class Object
