Diffuse Reflection - Polygon Rendering & Ray Tracing Methods
It is characteristic of light reflected from a non-shiny, dull surface. Objects illuminated solely through diffusely reflected light display an equal light intensity by all viewing directions. In Diffuse reflection light that is incident upon the surface is reflected uniformly in all directions and is attenuated via an amount dependent at the physical properties of the surface. As light is reflected uniformly in all directions the perceived illumination of the surface is not dependent upon the position of the observer. This models the light reflecting properties of matt surfaces, which is surfaces which are grainy or rough that tend to scatter the reflected light in each direction. This scattered light is termed as diffuse reflection.
