Abstract

A method and an apparatus for three-dimensional (3D) visual effect simulation are provided. A viewpoint movement distance is detected in a display plane. Subsequently, a first movement distance of a first graphic element in the display plane and a second movement distance of a second graphic element in the display plane are determined respectively according to the viewpoint movement distance. The first movement distance is not equal to the second movement distance. Further, a first location of the first graphic element is changed in the display plane according to the first movement distance, and a second location of the second graphic element is changed in the display plane according to the second movement distance.
