Point Light Attenuation

Point light rays are attenuated:

brightness =

lightIntensity
constant + linear*distance + quadratic*distance2

 

Method Default
void setPosition( Point3f pos ) 
0.0, 0.0, 0.0 
void setAttenuation( Point3f atten )
 1.0, 0.0, 0.0

light.setColor( new Color3f( 1.0f, 1.0f, 1.0f ) );
light.setPosition( new Point3f( 0.0f, 1.0f, 0.0f ) );
light.setAttenuation( new Point3f( 1.0f, 0.0f, 0.0f ) );
