Claim 6:
7. The method of claim 1, wherein the forming the carved mesh further comprises:
slicing the 3D model by the plurality of fitting planes, each of the plurality of fitting planes slicing the 3D model into a positive part and a negative part, the positive part of the 3D model being positioned on a positive side of the respective one of the plurality of fitting planes;
projecting each of the positive parts of the 3D model onto a corresponding fitting plane of the plurality of fitting planes to obtain a respective second silhouette;
obtaining an enlarged bounding square of the respective second silhouette on the corresponding fitting plane such that the respective second silhouette is included in the enlarged bounding square;
performing a Boolean subtraction operation to subtract the respective second silhouette from the enlarged bounding square to obtain a boundary loop of the respective second silhouette; and
forming a second 3D primitive of the second 3D primitives by extruding the boundary loop of the respective second silhouette in a normal direction from the positive side of the fitting plane corresponding to the respective second silhouette.
