Large-scale group performance animation synthesis method and device

Abstract

The invention provides a large-scale group performance animation synthesis method. The method comprises the steps of: firstly confirming original states of to-be-synthesized large-scale group performance animations and acquiring instance data of small-scale group performance animations; and then establishing group motion dual graphs, and synthesizing large-scale group performance animations according to the small-scale group performance animations. According to the large-scale group performance animation synthesis method, the small-scale group performance animations and the large-scale group performance animations which have apparently similar motion features are related with the large-scale group performance animations through the group motion dual graphs; by virtue of the group motion dual graphs, a user only needs to manually design or obtain the small-scale group performance animations by utilizing various known group motion capturing methods so as to automatically generate the large-scale group performance animations; and the purposes of editing and controlling the large-scale group performance animations by a designer can be realized by indirectly editing and designing the small-scale group performance animations.

Description

technical field [0001] The invention belongs to the field of computer graphics, in particular to the group synthesis technology. Background technique [0002] Group motion synthesis technology has received more and more attention in recent years, and it is widely used in many fields, especially the virtual rehearsal of large-scale performances and the synthesis of group motion special effects in the film industry. Group movements in these applications often achieve the purpose of simulation by displaying their macroscopic properties, such as hundreds of actors in a large-scale opening performance constructing a group formation with artistic shapes to express the theme of the conference or a movie In the movie, the specific tactical arrangement is shown through the confrontation scenes of the two armies with thousands of troops. Different from general crowd movements, the movement of groups in large-scale group performances and film and television needs to obey the director'...
