虚拟自动生产线动画干涉的隐藏替换研究

随着Web和计算机硬件技术的日益发展，虚拟现实技术在越来越多的领域发挥巨大作用。VRML(virtual reality modeling language)以平台独立性、低宽带要求、强交互性等特点在虚拟现实领域被广泛应用。目前，在使用VRML研制虚拟现实系统时，借助CAD软件建立场景的复杂模型是主流手段，但使动画场景的拼接成为难点。为解决虚拟自动生产线开发中的这一问题，笔者提出了简便高效的隐藏替换技术。该技术有效地解决了协调运动中的虚拟对象在特定时间和位置的动画拼接，保证虚拟自动生产线虚拟场景动态仿真的准确性和实现用户视觉上的连贯性。该隐藏替换技术具有高效、准确和简便的优点，较好的解决了传统拼接方法的效率低下和难度大的问题。

Research on Hiding-replacing in Animation Interference of Virtual Auto-product Line System

With the development of Web and computer hardware, Virtual Reality technique has huge effect in more and more fields. Because of platform independence, narrow bandwidth request and powerful interface characters, VRML(Virtual Reality Modeling Language) is widely used. Now, CAD software is often used in modeling when create virtual system. Thus, the single animation scenes have to be put together in later period. According to this problem, a high efficient and convenient way, using the hiding-replacing method to put one-step scenes together at the special time, is put forward. By this way, the veracity of simulation in the virtual auto-product line system is ensured, and the customs can get a coherent scene visually. In view of traditional way, it is high efficient, accurate and easy.
