| Abstract: | This paper introduces the principle of expressing a flexible body using spherical harmonic functions. Then it focuses on the implementation mechanisms of the virtual flexible body modeling method based on the multi-scale feature of the spherical harmonic functions. The experimental results show that the approach can achieve accurate object modeling and real-time expression. So it is very suitable for the areas which requires scene realistic higher such as collision detection of virtual reality, virtual surgery simulation and so on. |
