近几年发展起来的虚拟制造技术成为设计制造领域研究的热点，它对制造过程中的设计、加工、测量、装配和检验等提出了新的要求由于坐标测量机是制造系统的重要组成部分，为了满足虚拟制造系统的要求，说明了虚拟现实环境中坐标测量机动态图形建模与仿真的必要性，并介绍了利用三维图形开发语言OpenGL进行几何建模与现有其它几何建模方法的统一性和差别，以及用Open在虚拟环境中进行坐标测量机动态图形建模的方法和过程，最后提出了虚拟环境中坐标测量机仿真运行的硬件环境，虽然提出的方法是在坐标测量机机械结构及其层次模型的基础上研究的，但是该方法具有一定的普遍性，即可适用于其它类型机械结构的动态图形建模，动态图形建模是虚拟现实系统运行的基础。
The virtual manufacturing technology developed in recent years has become a hot research area in the field of design and manufacture. It puts forward new requirements on the design, processing, measurement, assembly and inspection in the manufacturing process. Because CMM is an important part of the manufacturing system, In order to meet the requirement of virtual manufacturing system, the necessity of modeling and simulation of the dynamic CMM in virtual reality environment is described. The unification of geometric modeling using the 3D graphics development language OpenGL and other existing geometric modeling methods is introduced Sex and difference, as well as with Open in the virtual environment coordinate measuring machine dynamic graphics modeling methods and processes, and finally proposed the virtual environment coordinate measuring machine simulation running hardware environment, although the proposed method is in the CMM mechanical structure And its hierarchical model, but the method has some universality that it can be applied to the dynamic graphics modeling of other types of mechanical structures. Dynamic graphics modeling is the basis of the virtual reality system operation.
