基于虚拟现实的家具系统研究 摘要 知识经济在全球范围内兴起，对我国传统的家具、窗帘行业提出了新的挑战。一方面，多样化、质量好、功能完善、造型优美、设计周期短、生产效率高等新特点大大提高了企业产品生产要求。手册加图板等传统的设计方法很难满足上述要求，计算机辅助设计成为不可缺省的手段，企业对定制化软件的需求越来越迫切另一方面，不管对于板式家具还是窗帘，业主都希望能够自行参与设计，使设计出的产品更好地体现自己的个性风格，而一套使用方便，具有良好三维体验效果的板式家具、窗帘搭建系统能够很好地满足业主这样的愿望。目前市场主流家具、窗帘的设计软件，品种繁多，但这些软件要么对用户要求太高，用户短时间内无法精通，要么在二维状态下进行操作，三维体验效果不佳。本文针对上述背景，研发了一套方便快捷的三维板式家具窗帘体验系统，很好地满足了市场需求。文中论述的主要内容如下： 将面向对象程序设计思想引入到三维板式家具设计与体验系统的设计与开发中。根据板式家具特点，将该系统划分为四个子系统：造型设计子系统、编辑修改子系统、工程图与报价产生子系统以及效果展示子系统，详细介绍了各个子系统的设计思想、具体算法以及开发过程。 采用群组设计思想，研发了一套便捷的三维窗帘设计与体验系统。该系统可让用户方便地选择不同类型的帘头、帘身、帘杆、纱等部件，快速搭建窗帘的三维整体效果，并可对窗帘整体旋转、移动，可实时替换窗帘的各个部件。 介绍了如何将设计完成的板式家具与窗帘融合到三维之家家居设计软件中，从而让业主体验板式家具与窗帘摆放在家中效果。 关键词：三维板式家具设计三维窗帘搭建面向对象 　 Abstract As the development of knowledge economy around the world, the traditional furniture and curtains industry is meeting a big challenge in China. On the one hand, the industry of panel furniture and curtains is meeting more and more high requirements such as the diversity of products, high quality, more functional, short design cycle and high production efficiency. It is difficult for traditional methods which use handbooks and drawing boards to meet the above requirements, CAD methods have become indispensable and now companies have a great desire to own customized softwares. On the other hand, regardless of panel furniture or curtains, the owners want to participate in the design with themselves, so that the product can better reflect their personal styles. As a result, a design system that is easy-to-use and with good 3D effect will meet the desire of the owners. Nowadays,The softwares of furniture and curtains which are widely used on the market are sundry , but they are either too difficult for users to learn that users can not be proficient in a very short period of time or the operations of which are under two-dimensional state that have a poor 3D effect. In the case above, this paper finally proposes a more functional, more convenient and easier operated 3D Computer-aided panel
