    摘要: A system and method for creating a three-dimensional graphic object is disclosed. The system comprises an outline-processing unit for modeling a first two-dimensional object by at least one outline, a curve-processing unit for modeling a second two-dimensional object by a closed curve, a curve-adjusting unit for adjusting the closed curve in response to the outline so as to generate a third two-dimensional object, a uniting unit for uniting the first and third two-dimensional objects to generate a-fourth two-dimensional object modeled by the adjusted closed curve and the at least one outline, a 3-D creating unit for generating the first, third and fourth two-dimensional objects three-dimensional to form a first three-dimensional object, a second three-dimensional object and a third three-dimensional object, respectively, and a graphics-combining unit for grouping two of the first, second and third three-dimensional objects for creating the three-dimensional graphic object in response to either a convex or a concave mode selection.
