Abstract :
The algorithm of shadowmap and its basic principle are studied in this paper. The cause of self-shadow and aliasing are also explained in a mathematical way. The paper presents a multi-sampling algorithm to smooth shadow, and reduce aliasing by increasing precision of depth information and making use of z-bias. The algorithm is implemented by DirectX3D. Experimental results show the feasibility of the algorithm.
