public class SpotLight

extends PointLight

SpotLight()

Create a spotlight.

SpotLight(float, float, float)

Create a spotlight which point in the direction from the origin to the point (x, y, z).

getDirection(Vector3)

setBeam(float, float)

Set the cutoff angle and the dropoff rate.

setDirection(float, float, float)

Set the spotlight's direction.

setDirection(Vector3)

  public SpotLight()

Create a spotlight. The new light is positioned at the origin and points in the positive Z direction. The cutoff angle is 30 degrees and the dropoff rate is 1.0.

  public SpotLight(float x,
                   float y,
                   float z)

Create a spotlight which point in the direction from the origin to the point (x, y, z). The new spotlight otherwise has the same properties as one created with the SpotLight() contstructor.

  public void setDirection(float x,
                           float y,
                           float z)

Set the spotlight's direction.

  public void setDirection(Vector3 direction)

  public void getDirection(Vector3 v)

  public void setBeam(float cutoffAngle,
                      float beamWidth)

Set the cutoff angle and the dropoff rate. The cutoff angle defines the cone which the spotlight illuminates. The intensity of the beam is constant inside the cone of angle beamWidth; it drops of linearly to zero at the cutoff angle. Angles are clamped to lie within [ 0, PI/2 ]
