Abstract: With the traditional method，it is easy to generate one parallax frame，but is difficult to make a series of parallax animation quickly．The viewing method of the parallax animation is introduced in this paper，and according to the features of camera data in the popular animation software，the automatic generating algorithm of parallax animation is also given．Images，including images of left viewpoint and right viewpoint and composite image，are presented for the parallax animation of the dynamical simulation of an engine assembly．
