Basic scene No lighting applied, each object within the scene is displayed with its colour. Each object looks like a silhouette with no visible detail. |
 |
|
Scene with ambient light (and emissive material) Ambient lighting is now applied to the scene. Ambient lighting is applied evenly to an object. So, each object still looks like a silhouette with no visible detail. However the lightness of the scene can be controlled. But, note that the “light” is not affected by the ambient light as it only has an emissive material. |

|
Directional light A directional light is added to the scene. |
 |
|
Directional light – fragment shader Again directional light is added to the scene. However, the lighting calculations are done in the fragment shader, making the lighting more accurate. |
 |
|
Directional light with materials (frag) Support for all materials (ambient, emissive, diffuse and specular) is added to the scene. Setting these values appropriately simulates different materials such as gold or copper. |
 |
|
Scene with point light and materials (frag) A point light is added to the scene. A point light has a position as well as a direction so as it approaches an object it has a greater effect. |
