Research on Behavior Control Method in 3D Virtual Animation Design Based on the Purpose of Improving the Effect of Overseas Dissemination

In order to improve the overseas dissemination effect of 3D (Three-dimensional) animation, this paper starts from the perspective of animation character behavior control to improve the dynamic texture of animation and enhance the audience's visual experience. Moreover, this paper designs and verifies the behavior control system of mobile animation character model based on the mathematical model. In addition, the initial animated character model is used to collect and summarize the working data, and the targeted hierarchical behavior design method is formulated by analyzing and adjusting the target tasks of the moving animated character model, which can generate the real-time behavior track meeting the requirements, strengthen the motion control, pose data estimation and safety control of the behavior, and realize more efficient reaction control. Finally, the experimental results verify the effectiveness of this method, which has a certain effect on improving the overseas dissemination effect of animation.
