三维空间中造型交互式移动的实现

Realization of Molding Interactive Movement in Three-dimensional Space

针对虚拟装配过程中,经常涉及到的造型的空间移动问题,研究了三维空间中造型交互式移动的方法。通过分析虚拟现实建模语言中的传感器节点以及脚本节点的工作原理及特点,确定了造型交互式移动的实现流程和方法。结合实例,实现了三维模型随浏览者鼠标拖动而沿XOY平面及法向轴方向的同步移动,并且给出了相应的程序代码。这一交互过程相对于造型沿三坐标轴方向的移动,移动效率显著提高,因此对于虚拟场景中造型的交互式移动具有重要的意义。

Molding space skip was usually involved in the process of virtual assembly. Because of that, method of molding interactive movement in three-dimensional space was achieved. By analyzing working principle and characteristics of sensor node and script node in virtual reality modeling language,make sure the procedure of model＇s interactive movement. This paper realized three-dimensional molding synchronous movement along XOY plane and normal axis according to visitor＇s mouse drag. It was presented by an example,and some program code was given. Compared with the process of model＇s movement along three-axis,moving efficiency was greatly improved. So it is of great significance to model＇s interactive movement in virtual environment.
