public class RectangularPyramid
extends SensorFieldOfView

A sensor volume with a rectangular cross section and a radial range limit. The half angles define the outer boundaries of the volume, and the radial range closes the volume, forming a sensor volume in the shape of a rectangular pyramid.

The vertex of the volume is located at the origin and the sensor principal direction is along the positive z-axis. Half angles measured from the principal direction and in the direction of the x-axis and y-axis define the extent of the rectangular cross section. The range limit measured radially from the origin closes the volume.

Constructor Detail

RectangularPyramid

public RectangularPyramid()

Constructs a volume with a default definition, in which the XHalfAngle (get / set) and the YHalfAngle (get / set) are equal to Constants.HalfPi radians.

RectangularPyramid

public RectangularPyramid(double xHalfAngle,
                          double yHalfAngle)

Constructs a volume of infinite radius with the provided parameters.

Parameters:

xHalfAngle - The half angle measured from the principal direction and in the direction of the x-axis.

yHalfAngle - The half angle measured from the principal direction and in the direction of the y-axis.

RectangularPyramid

public RectangularPyramid(double xHalfAngle,
                          double yHalfAngle,
                          double radius)

Constructs a volume of limited radius with the provided parameters.

Parameters:

xHalfAngle - The half angle measured from the principal direction and in the direction of the x-axis.

yHalfAngle - The half angle measured from the principal direction and in the direction of the y-axis.

radius - The radial limit of the volume. This is the maximum range at which the sensor can detect a target.

Method Detail

getIsConnected

public boolean getIsConnected()

Gets a value indicating whether the figure is connected.

Specified by:

getIsConnected in class Figure

onRadiusChanged

protected void onRadiusChanged()

Called after the Radius (get / set) property changes.

Overrides:

onRadiusChanged in class SensorFieldOfView

getXHalfAngle

public final double getXHalfAngle()

Gets the half angle measured from the principal direction and in the direction of the x-axis.

Throws:

ArgumentOutOfRangeException - Thrown when the half angle is less than or equal to zero or greater than Constants.HalfPi radians.

setXHalfAngle

public final void setXHalfAngle(double value)

Sets the half angle measured from the principal direction and in the direction of the x-axis.

Throws:

ArgumentOutOfRangeException - Thrown when the half angle is less than or equal to zero or greater than Constants.HalfPi radians.

getYHalfAngle

public final double getYHalfAngle()

Gets the half angle measured from the principal direction and in the direction of the y-axis.

Throws:

ArgumentOutOfRangeException - The half angle must be greater than zero and less than or equal to Constants.HalfPi radians.

setYHalfAngle

public final void setYHalfAngle(double value)

Sets the half angle measured from the principal direction and in the direction of the y-axis.

Throws:

ArgumentOutOfRangeException - The half angle must be greater than zero and less than or equal to Constants.HalfPi radians.

encloses

public boolean encloses(@Nonnull
                        Cartesian point)

Indicates if the provided point is inside the volume.

The point parameter must be expressed in the same coordinate frame that the volume is defined in.

Specified by:

encloses in class Solid

Parameters:

point - The point to evaluate.

Returns:

true if the point is inside the volume and false if the point lies on the boundary or outside of the volume.

getEnclosureDescriptions

public EnclosureDescriptionCollection getEnclosureDescriptions()

Gets the list of descriptions for the enclosure functions for this solid.

Specified by:

getEnclosureDescriptions in class Solid

Returns:

The list of enclosure descriptions.

getProjection

public SensorProjection getProjection(Ellipsoid ellipsoid,
