What Is Meant By Ambient, Diffuse, Specular And Emissive Lighting?
Materials are typically defined by using ambient, diffuse, specular and emissive colors. It is an effect to catch the nuances of real world light material surface interaction. Ambient and diffuse lights are grouped together and emissive light is specified only for objects that generate their own light. Ambient lighting is just the general environmental illumination or we can say when there is no particular light. Ambient light relies upon no light in the scene. The ambient light is estimation for global illumination in the environment. The light of surface when the surface is perfectly matte is called diffuse light. Diffuse lights depend only on the angle of the light to the surface. Diffuse light is reflected in all directions. Specular light mimics the shininess of a surface. Specular light intensity is a function of the light reflection angle of the surface. When we want an object to glow in a scene then we use emissive light. Emissive light is an additional color source that is add
