Constructor Details

RayDouble

public RayDouble(Vector3D origin,
 Vector3D direction)

Constructor, sets the starting position of the Rayd and the direction.

Parameters:

origin - The starting position

direction - The direction

Method Details

cpy

public RayDouble cpy()

Returns:

a copy of this Rayd.

getEndPoint

@Deprecated
public Vector3D getEndPoint(float distance)

Deprecated.

Use getEndPoint(Vector3D, float) instead. Returns the endpoint given the distance. This is calculated as startpoint + distance * direction.

Parameters:

distance - The distance from the end point to the start point.

Returns:

The end point

getEndPoint

public Vector3D getEndPoint(Vector3D out,
 float distance)

Returns the endpoint given the distance. This is calculated as startpoint + distance * direction.

Parameters:

out - The vector to set to the result

distance - The distance from the end point to the start point.

Returns:

The out param

mul

public RayDouble mul(Matrix4D matrix)

Multiplies the Rayd by the given matrix. Use this to transform a Rayd into another coordinate system.

Parameters:

matrix - The matrix

Returns:

This Rayd for chaining.

toString

public String toString()

Overrides:

toString in class Object

set

public RayDouble set(Vector3D origin,
 Vector3D direction)

Sets the starting position and the direction of this Rayd.

Parameters:

origin - The starting position

direction - The direction

Returns:

this Rayd for chaining

set

public RayDouble set(float x,
 float y,
 float z,
 float dx,
 float dy,
 float dz)

Sets this Rayd from the given starting position and direction.

Parameters:

x - The x-component of the starting position

y - The y-component of the starting position

z - The z-component of the starting position

dx - The x-component of the direction

dy - The y-component of the direction

dz - The z-component of the direction

Returns:

this Rayd for chaining

set

public RayDouble set(RayDouble Rayd)

Sets the starting position and direction from the given Rayd

Parameters:

Rayd - The Rayd

Returns:

This Rayd for chaining

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
