Abstract: In this paper, we analysis the reason that causes objects' jagged edges in ray tracing, discuss several kinds of antialiasing methods, on which we propose and implement an adaptive random sampling . The experimental results show that the antialasing algorithm can effectively diminish objects' jagged edges.
