探讨了建立虚拟现实系统首要的和关键性的问题——建模技术,需要根据虚拟现实系统的特点确定不同的建模方式。真实性的模型数据量相当大,如何减少模型的数据量成为虚拟现实系统的又一难题,因此,建立模型后需要对模型进行优化成为虚拟现实系统的必然趋势。
Molding technology,the pivotal and principal issue in establishing the system of virtual reality,has been discussed.Different molding methods should be adopted according to the characteristics of virtual reality system.As the actual data of modeling is considerably large,how to reduce the data of modeling in the system of VR turns to be another hard problem.So model optimization is inevitable in the system of VR.
