Constructor Detail

RightCircularCone

public RightCircularCone(Vector3D inOrigin,
                         Vector3D inDirection,
                         double inAngle,
                         double inLength)

Build a elliptic cone from its radius, the height, the origin (apex) and direction of its axis

Parameters:

inOrigin - the origin of the axis

inDirection - the direction of the axis

inAngle - the angle of the cone

inLength - the height of the cone on its axis

Throws:

IllegalArgumentException - if the angle or the height is negative or null, or if the direction vector has a null norm.

Method Detail

getLength

public double getLength()

Returns:

the height

getOrigin

public Vector3D getOrigin()

Returns:

the origin

getAngle

public double getAngle()

Returns:

the angle

getDirection

public Vector3D getDirection()

Returns:

the direction

intersects

public boolean intersects(Line line)

Tests the intersection with a line.

Specified by:

intersects in interface Shape

Parameters:

line - the line

Returns:

true if the line intersects the shape

getIntersectionPoints

public Vector3D[] getIntersectionPoints(Line line)

Compute the intersection points with a line.

Specified by:

getIntersectionPoints in interface Shape

Parameters:

line - the line

Returns:

the intersection points if they exist. If no intersection is found, the dimension is zero

distanceTo

public double distanceTo(Line line)

Computes the distance to a line.

Specified by:

distanceTo in interface Shape

Parameters:

line - the line

Returns:

the shortest distance between the the line and the shape

closestPointTo

public Vector3D[] closestPointTo(Line line)

Computes the points of the shape and the line realizing the shortest distance. If the line intersects the shape, the returned points are identical : this point is the first common point found.

Specified by:

closestPointTo in interface Shape

Parameters:

line - the line

Returns:

the two points : first the one from the line, and the one from the shape.

toString

public String toString()

Get a representation for this elliptic cone. The given parameters are in the same order as in the constructor.

Overrides:

toString in class Object

Returns:

a representation for this elliptic cone
