摘　　要：对复杂异形弹簧的实体造型技术进行了研究,着重阐述了弹簧实体表面的三维离散技术,提出了一种针对螺旋体与异形弹簧末端连接部分进行光滑处理的方法,避免了实体造型时出现缝隙,并在C++Bu ilder环境下,以OpenGL为工具,实现了异形弹簧的造型和显示。该方法显示效果逼真,实用性强,为异形弹簧的设计和制造提供了新途径。The solid modeling of a complicated special-shape spring is difficult because of its complex spatial shape. This paper studies its 3D modeling technology using OpenGL. The emphasis is on how to disperse the spring＇s solid surface. In a local coordinate system, the spring surface is divided into equal points. Their global coordinates can be obtained using coordinate transformation. In order to avoid the gap between a helix and the end of a special-shape spring, the paper presents an effective method for creating smooth transition. The solid modeling is created using OpenGL and C ＋ ＋ Builder. The method provides a new approach to the visual design and coiling of special-shape springs.
