Constructor Detail

PointLight

public PointLight(double lightX,
                  double lightY,
                  double lightZ,
                  java.awt.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()

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
