A Calculation Method for Ship Hydrostatic Properties Based on the Subdivision Curve and Surface Theory

Curved surface shaping of ship hull by subdivision surface was presented, a new calculation method for ship hydrostatic properties was put forward based on the formulas of geometry property. In the paper, two formulas were given to Calculate the geometry properties of polygon and polyhedron. The hydrostatic properties of designed mathematical ship models were calculated, and the numerical results were compared with the theoretical results and those by other methods, which validated the proposed method.
