Abstract: The paper introduces an application package which we developed called DXVHSDK,based on DIRECT 3D technology. The functionality of the package includes loading 3D-virtual humans and making control of their motions with efficient rendering.It is reliable,expansible and capable of producing complex actions by virtual humans.DXVHSDK can be used in various application fields such as simulation,entertainments,intelligent human-machine interaction.By using DXVHSDK,a prototype system is developed to control virtual human's motion.
