Image, generate the video file.
In this embodiment it is possible to first generate the multiple image of video file, the multiple image next life of generation is then based on
Into video file.Wherein, each two field picture of generation is all the picture that renders to obtain according to each visual angle to generate.
In an embodiment of the present invention, it is proposed that by each visual angle, a corresponding picture is synthesized the following two kinds respectively
Obtain the scheme of a two field picture：
Scheme one：
From each visual angle respectively corresponding to the contents of perhaps multiple rows in multiple row is chosen in a picture；Will be from
Each visual angle respectively corresponding to the content of interior perhaps multiple rows of multiple row chosen in a picture carry out permutation and combination,
To generate a two field picture.
Further, a kind of in scheme, a picture corresponding to any visual angle is in the frame figure in the multiple visual angle
