【Abstract】 Based on the high resolution dataset of Virtual Chinese Male-No.1 and the virtual reality development toolkit Open Inventor,the visual scene graph and the haptic scene graph were matched in the three-dimensional (3D) space using the simulation system which integrated the active stereo glasses and the force-feedback device.In this paper,we described the developing requirements for medical training simulation,the implementation strategy for the synchronous 3D visual- haptic match was analyzed,and some valuable results of the experiments on 3D synchronous match and the simulated in- jection were presented.The results demonstrated that the simulation system can provide synchronous 3D visual-haptic match,which can lead to the realistic medical training simulation.更多还原
