Abstract: A new method for animation is proposed in this paper, which integrates level set models into 3D animation . Deformable models are used for designing and animating complex objects, the level set method is introduced to vary the topology of the models. At the same time, an novel method for extending speed is developed to accurately modeling. In order to improve the speed of modeling, a fast algorithm is proposed by integrating a narrow band method and the mul scale algorithm. The experimental results are also included to show the potential of the newly presented method for animating objects with complicated shape and topologies.
