A new approach for long distance virtual scene smooth transition is developed. Firstly,the scene pictures were processed based on wavelet transform image fusion. Then a TIP model for each fusion image was given,and the models were linked seamlessly by principle of projective geometry,and the coherent 3D virtual scene was rendered at last.. The experiment result shows that this method eliminates the limit on the tour length of virtual scene in that of single TIP,and can make the tour into long virtual scene smoothly.
