Introduction to fog
  
To compute the fog color, we should use an equation that allows us to define the way fog density behaves according to the distance between the camera and a given vertex. The aim of this equation is to compute a fog factor that will allow to mix the fragment color with the fog color. Vanda Engine 1 uses exponential method, because of its more realistic fog rendering possibilities.
 
fogFactor = e^(-(density * z)^2)
 
z is the distance between the camera and the currently processed vertex.
