Constructor Detail

PointLight

public PointLight(double lightX,
                  double lightY,
                  double lightZ,
                  Color lightColor)
Method Detail

getLightX

public double getLightX()
Returns:
the light's x position

getLightY

public double getLightY()
Returns:
the light's y position

getLightZ

public double getLightZ()
Returns:
the light's z position

isConstant

public boolean isConstant()
Specified by:
isConstant in interface Light
Overrides:
isConstant in class AbstractLight
Returns:
true if the light is constant over the whole surface

getLight

public final void getLight(double x,
                           double y,
                           double z,
                           double[] L)
Computes the light vector in (x, y, z)

Parameters:
x - x-axis coordinate where the light should be computed
y - y-axis coordinate where the light should be computed
z - z-axis coordinate where the light should be computed
L - array of length 3 where the result is stored
