PointLight

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

Method Detail

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

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()

Returns: true if the light is constant over the whole surface
