Constructor Detail

Ray

public Ray(Vector3 origin,
   Vector3 direction)

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

Parameters:

origin - The starting position

direction - The direction

Method Detail

cpy

public Ray cpy()

Returns:

a copy of this ray.

getEndPoint

public Vector3 getEndPoint(Vector3 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 Ray mul(Matrix4 matrix)

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

Parameters:

matrix - The matrix

Returns:

This ray for chaining.

toString

public String toString()

Overrides:

toString in class Object

set

public Ray set(Vector3 origin,
      Vector3 direction)

Sets the starting position and the direction of this ray.

Parameters:

origin - The starting position

direction - The direction

Returns:

this ray for chaining

set

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

Sets this ray 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 ray for chaining

set

public Ray set(Ray ray)

Sets the starting position and direction from the given ray

Parameters:

ray - The ray

Returns:

This ray for chaining

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
