diff | Diffuse intensity |
ambi | Ambient intensity |
njCnkSetSimpleLightIntensity( 1.0f, 0.0f );
In this case, the spot at the opposite of 90 degrees from the light is fully dark. Therefore, a certain amount of ambient light should always be set.
njCnkSetSimpleLightIntensity( 1.0f, 0.2f );
In this case, the image does get darker than 20%.
njCnkSetSimpleLightIntensity( 0.0f, 1.0f );
With 100% for both items, there is no shadow. When the result of light calculation is 1.0 or higher, the light acquires a specular quality.
