Method Detail

createPointLight

public static Light createPointLight(float x,
                                     float y,
                                     float z)

Create a a point Light.
The ambient color will be (0,0,0,1)
The diffuse color will be (1,1,1,1)
The specular color will be (1,1,1,1)
The position will be (0,0,1)
The constant attenuation will be 1
The linear attenuation will be 0
The quadratic attenuation will be 0

Parameters:

x - The x coordinate of the position

y - The y coordinate of the position

z - The z coordinate of the position

Returns:

The Light

createDirectionalLight
