Today I was introduced to a series of videos and the implementation of lighting in video games, the videos are made by Jeremy Vicker and he will explain how lighting works through out his tutorial videos.
In the first video he begins by explaining that he has had a lot of experience with lighting via his job therefore I know that he is a credible source. I wasn't really that familiar with the processes that he explained that we would be going through through out his tutorials so I look forward to learning about them and applying them to the lighting on my level.
In the second video he explained about the lighting effects on the various types of effects that lighting would have on various materials and whether that light would be absorbed, reflected or refracted. He then explain light absorption and how black objects and materials will absorb light where as coloured materials will absorb all spectrum's of light except from the colour of the material, instead this light is bounced off the material. He then went on to explain how light is reflected off various objects, objects that have a smooth surface will reflect light very sharp and clearly due the light being perfectly reflected and bounced from the smooth surface. However whenever light his an un-smooth surface it will be not be reflected perfectly and will instead be bounced in all different directions.
In the third video Jeremy explained how the materials in a level should affect the lighting of the level based on weather the material is reflective, specular or diffuse. He then talked about various light types that can be used, when explaining about directional lights he explained that it is used as the main light source which I am familiar with from previous units. He explained that the light coming from a point and/or spotlight would be reflected the same as a directional light but just on a smaller scale.
