中文摘要：

腰椎治疗仪的实时仿真能给操作者提供实时直观的仪器状态。基Mesa／OpenGL，分别在Windows和Linux平台下实现了三维多功能腰椎治疗仪的动态实时仿真。详细描述了其实现步骤，分析了在两种平台下程序的异同之处，并指出编程中应该注意的细节。根据实时动态输入的治疗仪参数实现实时动态仿真。

英文摘要：

The real-time simulation of lumbar curer provides real-time and visual state of the instrument for operators. Based on Mesa/ OpenGL, the real-time dynamic simulation of a multifunction lumbar curer is implemented under Windows and Linux platforms respec- tively. The paper describes its detailed implementation steps, analyzes the two platforms program similarities and differences, and discusses the programming details that should be cared. The real-time dynamic simulation is produced according to real-time dynamic input param- eters of the instrument.
