Combine computerized tomography technology well for fabricating made bone model and bone substitute rapidly and precisely, this paper has brought forward a new way which generates directly data of 3D objects model by interbedded interpolating. Firstly, using the contour tracing algorithm to trace the manipulated contour BMP, the contour point chain was attained. Calculates the least distance of these corresponded contours around the superposition point, the best orientation was attained. Due to the larger distance of CT images, the paper uses its optimized least distance algorithm to attain lengthways contour point chain which is interpolated with the third power non-uniform B-spline.Using a plane in the middle of two slices to intersect these lengthways contour line, the contour's character point was attained which is middle layer information of model. Lastly, links the contour character point on the adjoined slice to generate triangular facet model.
