The invention relates to a shadow rendering method. The method comprises the following steps of: obtaining a sample; determining a first depth reference plane (Z1) and a second depth reference plane (Z2) for the region to be rendered, mapping a depth value of a first depth reference plane (Z1) relatively closer to the light source (300) in the first depth reference plane (Z1) and the second depthreference plane (Z2) as a maximum depth reference plane (Zmax); and mapping a depth value of a second depth reference plane (Z2) relatively further away from the light source (300) in the first depthreference plane (Z1) and the second depth reference plane (Z2) as a minimum depth reference plane (Zmin). According to the invention, the flickering of shadows can be reduced.
