Research On Rapidly Generating3-D Ship General Arrangement Model

The paper researches on a rapid3-D general arrangement modelling applied to general arrangement design of vessels.In the modern computer-aided design,3-D model plays an increasingly important role.This system brings3-D reconstruction and3-D model technology into rapid ship general arrangement modelling to create a convenient, practical and efficient software for ship general arrangement design.in the paper, the development situation and development trend of domestic and foreign of ship3-D modelling are discussed, as well as3-D reconstruction. The technology issues which need to address in rapid ship general arrangement modelling are analyzed, which [EB/OL]. http://www.pep.com.cn/rjqk/sjtx/sxzz/pg2005_l2z5/201101/t20110106₁006290.htm the paper.In this paper, hull surfaces are expressed by NURBS surfaces, and rapid bulkhead reconstruction is solved by an intersection algorithm based on NURBS surface and plane intersection; in addition,3-D reconstruction based on feature recognition technique is studied [EB/OL]. http://www.pep.com.cn/sxzz/js/ztts/kg/201008/t20100830₈30998.htm superstructure reconstruction. On the other hand, a rapid3-D ship general arrangement modelling system is programmed with VC++programming software and OpenGL graphics library, within outfitting data management based on Access database and DAO classes.The ship system also provides a new direction for3-D modelling during the process of ship design.The interface of system has a simple usage and be practical.Users can import data files quickly to obtain three-dimensional model of the ship general arrangement, which improves the efficiency of general layout and design modelling.The system has been validated with an example ship in the paper.
