The nonlinear stability of three-dimensional disturbances for the Blasius boundary layers is studied. We adopted here the high accuracy method of using the expansions in orthogonal functions along the normal direction and the effective algebraic mapping to deal with the problem in the infinite region. The initial solutions of two-dimensional harmonic waves are given by Landau expansion, and the mean-flow-distortion is calculated by the approximation equation.

According to Professor Shi Changjie, the reason for production with both 2D and 3D software is to preserve the original illusory world of Jimmy and to create multiple yet realistic impressions of space."A Fish With a Smile " achieves this feat through production despite the incredibility of the outside world, and really constructed from the two-dimensional world as depicted on flat surface a three-dimensional world of strangeness and wonder. 3D director Duan Yilun has said that ordinarily, 3D hardware is used mainly to express special 3D spaces or different angles in film, but in accordance with the light colors of Jimmy's original works and in search of a realistic space that can arise from the pages of the story, the sculpting of the set, light direction and camerawork have all transformed into high difficulty, high skilled manipulations.
