Abstract: We consider the instance of the 3-dimensional visual simulation platform controlled by the real-time hand model,which is developed by visual C++ and OponGL.To construct the 3-dimersional model of hands,the mathematical method and the corresponding algorithm are introduced in datail.The software design of this platform makes use of the interface simulating real human hands.As well,the function of real-time scraching has been implemented,compared to other similar systems.This platform is some extensible and friendly.
