摘　　要：基于三维建模软件Creator建立塔式起重机工作的真实场景模型,探讨场景建模和纹理制作方法与技巧,并使用模型优化技术,减少模型面数、节点数,有效地节省系统资源开支,提高系统的运行速度。在VC++中调用Vega函数编程驱动模型,实现用户和场景实时交互的性能,为开发塔式起重机虚拟操作培训系统虚拟现实软件奠定了基础。The paper studies the function and composition of a virtual operation training system for tower cranes and investigates scene modeling techniques of visual simulating.The real working scene of the tower cranes is set up based on three-dimensional modeling Creator software.The methods and skills of modeling and texture making are researched.Model optimization techniques are used to reduce the number of surfaces and nodes,so that the system resources are saved and the system speed is improved.Model-driving is realized in VC＋＋ by calling Vega functions,which achieves the performance of real-time interaction between users and the scene.The techniques provide the foundation for developing the virtual real software of virtual operating system for training operators.
