Realtime hybrid shadow algorithm using shadow texture and shadow map

Shadow plays key roles in making images look realistic and you feel spatial sense within the scene. Shadow map and shadow texture are the most famous algorithms for these effects, but both methods have some problems as is well-known. Shadow Map has the aliasing and stripe pattern problem whereas shadow texture algorithm doesn't have these problems but can not create shadows on themselves (self-shadows). We solved these problems by applying both algorithms at the same time. Our method shows more effective performance and higher quality compared to each existing algorithm.
