However, shadow has lots of benefits, but it is very complex for computer to work that realistic shadow and program performance can not both considered. Hence, there are many algorithms researched to reach the goal. The thesis stresses on the generating of soft shadow. It uses shadow map to draw the part of hard shadow and smoothie map to soft the aliasing from shadow map. This is the part of soft shadow. Among them, shadow map has a strong point of hard dependence which can increase algorithm performance.
