针对传统船舶静水力特性计算方法存在的不足，编写C++程序对加密型值表自动识别和读取，建立了船舶三维数据库。对实船正浮状态不同吃水时的各种静水力参数进行计算，与装载手册提供的数据进行对比和分析，说明了该方法的高精确性；运用坐标系矩阵变换和Sutherland-Hodgman剪裁算法计算任意浮态下船舶排水体积和浮心，与装载手册中提供的纵倾数据相比较，验证了该计算方法的正确性与通用性。

Aiming at the shortcomings of traditional calculation methods of hydrostatic performance for the vessel, a VC program is written to identify and read the densified table of offsets automatically. A three-Dimensional ship database is established. Hydrostatic performances of a vessel are calculated under upright condition and in different draft. In order to prove the high accuracy of present method, a comparison with the data provided by the loading manual is made. Volume of displacement and center of buoyancy in free floating condition are calculated by the use of coordinate transformation and Sutherland-Hodgman clipping algorithms. Comparing with the data provided in the loading manual, the validity and generality of present method is verified.
