System and method for creating three-dimensional graphic object having convex or concave portions

A method of creating a three-dimensional graphic object, comprising the steps of:

• (a) selecting a first two-dimensional object modeled by at least one outline and a second two-dimensional object modeled by a closed curve;
• (b) automatically adjusting said closed curve in response to said at least one outline so as to generate a third two-dimensional object;
• (c) uniting said first and third two-dimensional objects to generate a fourth two-dimensional object modeled by said adjusted closed curve and said at least one outline;
• (d) creating three-dimensionally a portion of said fourth two-dimensional object bounded between said adjusted closed curve and said at least one outline and a portion of said third two-dimensional object bounded by said adjusted closed curve to form a first three-dimensional object and a second three-dimensional object, respectively;
• (e) grouping said first and second three-dimensional objects to create said three-dimensional graphic object;
• and
• (f) displaying the three-dimensional graphic object.

A system for creating a three-dimensional graphic object, comprising:

• first means for modeling a first two-dimensional object by at least one outline;
• second means for modeling a second two-dimensional object by a closed curve;
• third means for automatically adjusting said closed curve in response to said at least one outline so as to generate a third two-dimensional object;
• fourth means for uniting said first and third two-dimensional objects to generate a fourth two-dimensional object modeled by said adjusted closed curve and said at least one outline;
• fifth means for creating said first, third and fourth two-dimensional objects three-dimensionally to form a first three-dimensional object, a second three-dimensional object and a third three-dimensional object, respectively;
• sixth means for grouping two of said first, second and third three-dimensional objects for creating said three-dimensional graphic object in response to a mode selection;
• and
• seventh means for displaying the three-dimensional graphic object.
