基于虚拟现实技术的原型设计机理研究

PRINCIPLE OF VIRTUAL REALITY BASED PROTOTYPING DESIGN

把虚拟现实技术与ＣＡＤ设计环境结合起来，通过将人引入概念设计回路，提出了基于约束的面向对象建模方法，形成了基于虚拟现实技术的原型设计系统ＶＲＰＳ，并探讨了系统的组成和实施机理。比较真实地反映了人在产品设计行为中的思维过程，从而克服了传统ＣＡＤ系统的多种缺陷。

Through connecting virtual reality (VR) technique into CAD environment, and introducing human to conceptual design loop, a kind of VR based object oriented modeling is given, a VR based system VR PS is constructed. The practice and frame of the system are discussed, which represents human in the design loop and overcomes the shortcoming of conventional CAD system.
