Research on Behavior Control Method in 3D Virtual Animation Design

In order to improve the effect of behavior control in 3D animation design, this paper combines 3D intelligent control algorithm to build model. In order to obtain high quality virtual human sign language animation, this paper proposes a new automatic generation technology of virtual behavior animation to realize intelligent control of behavior. According to the behavior control requirements of animation objects, the control model iIE can be constructed. In 3D virtual operation environment, the model and scene are built according to the size and style specified by technicians, and the animation parameters are flexibly adjusted according to the performance effect. After building the model, the method proposed in this paper is evaluated and analyzed with experiments, and the experiments verify that this technology has high applicability.
