《海军建筑原理》系列：约翰·莱彻（John Letcher）的《船舶几何》（The Geometry of Ships）由J.Randolph Paulling（2009）编辑，尽管仍有传统的船舶线型手工整流罩艺术的实践者，从小型游艇到最大的商业和海军舰艇，大多数船型的几何结构现在几乎都是使用一个商业化的船体建模软件包开发的。除船体建模和显示功能外，此类软件通常还包括计算静水力学、稳定性和其他船体特性的例程。它可以是基于计算机的综合设计和制造系统的一部分，也可以包括在用于货物装载监测和损坏控制的基于计算机的舰载操作系统中。本卷首先介绍这些船体建模系统的理论基础，其次介绍利用这些模型通过数学方法计算船体几何、浮力和其他特性的程序。重点是一些不同的船体几何建模方法背后的术语和基本原理，目的是提供所需的理解，以智能地使用现有和未来的工具。包括曲面的连续性和光顺性、B样条和NURBS表示、直纹和可展曲面、细分曲面以及静水力学性质和初始稳定性等经典计算主题。这是一个主题领域，其特点是不断创新和新的软件产品，因此这里的目标是提供了解和跟上该领域新发展所需的基础。
Principles of Naval Architecture Series: The Geometry of Ships by John Letcher Edited by J. Randolph Paulling (2009) Although there are still practitioners of the traditional art of manual fairing of ship lines, the geometry of most hull forms ranging from small yachts to the largest commercial and naval ships are now almost invariably developed using one of the commercially available hull modeling software packages. Such software normally includes, in addition to the hull modeling and display functions, routines for the computation of hydrostatics, stability and other hull properties. It may form a part of a comprehensive computer-based design and manufacturing system or it may be included in a shipboard computer-based operational system used for cargo load monitoring and damage control. The present volume presents first, the theoretical basis for these hull modeling systems and second, the procedures for computing hull geometric, buoyancy and other properties by mathematical methods utilizing such models. The emphasis is upon the nomenclature and fundamentals underlying several different methods of hull geometrical modeling with the intention of providing the understanding needed to use intelligently both existing and future tools. Some topics included in the volume are continuity and fairness of surfaces, B-spline and NURBS representation, ruled and developable surfaces, subdivision surfaces, and classic computational topics such as hydrostatic properties and initial stability. This is a subject area characterized by a continuing stream of innovation and new software products so the objective here is to present the basis needed to understand and keep abreast of new developments in the field.
