A new interactive approach of 3D modeling reconstruction from contours

3D modeling reconstruction from contours is an important problem in 3D visualization. At present, many approaches are proposed to solve this problem, but these approaches can not satisfactorily solve 3D modeling reconstruction based on the complex and poor transitional contours with special occupational demand. In this paper, we propose a new interactive method to solve this complex problem which based on the present approaches. The new approach use control line to solve complex tiling problem and use assistant branching information, like point, curve and face, to solve branching problem. The new approach are applied in 3D geologic body modeling with complex ore contours. The result of the application show that the new approach can control the model more flexibility when dispose complex contours.
