基于Windows的NUBLINE船型设计系统

NUBLINE HULL FORM DESIGN SYSTEM BASED ON WINDOWS

基于Windows的NUBLINE船型设计系统是基于多重节点B样条和面向对象设计技术的、运行于Windows之上的计算机辅助船型设计系统。本文叙述了NUBLINE系统从工作站版本、DOS版本到Windows版本的发展过程、使用面向对象设计技术的数据结构和程序流程、用B样条技术表达线型的数学原理，以及基于Windows平台的界面设计的特点等。

NUBLINE hull form design system developed by MARIC adopts cubic nonuniformB-spline curves with multiple knots and object-oriented technology. The development pro-cess of NUBLINE system from workstation version, DOS version to Windows version,data structures and program flow charts of using object-oriented design technology, math-ematical principles to represent a hull form by using B-spline technology, and featuers ofuser-interface design based on Windows are described.
