Device for generating shadow captions based on structures of characters

The embodiment of the invention discloses a device for generating shadow captions based on structures of characters, which comprises a decomposition module, a placement module, a superposition module and a stunt module, wherein the decomposition module is used for decomposing caption characters into character blocks and decomposing caption shadow into shadow blocks according to the structures of the characters; the placement module is used for placing the character blocks and shadow blocks which are decomposed by the decomposition module on different white boards respectively in a unique corresponding mode of texture coordinates; the superposition module is used for superposing the white boards on which the character blocks and the shadow blocks are placed by the placement module to generate the shadow captions, and the stunt module is used for realizing the stunt of the shadow captions by the movement of the white boards on which the character blocks and the shadow blocks are placed by the placement module. The device for generating the shadow captions based on the structures of the characters achieves the effect of rapidly generating the shadow captions which have various modes.
