虚拟现实技术在园林设计中的应用研究

虚拟现实技术是一种先进的计算机用户接口技术,它通过给用户提供视觉、听觉、触觉、嗅觉、味觉等各种直观而自然的实时感和交互手段,最大限度方便人机的交互操作,而不需要进行繁琐的敲打键盘输入,以提高整个系统的工作效率。虚拟现实有沉浸性、交互性和构想性三个基本特征。虚拟现实技术应用于园林规划设计可以得到全方位的观察和设计效果,同时可以展示园林空间的整体信息,通过互联网进行远距离浏览、辅助设计、辅助决策和公众参与。虚拟现实技术在园林设计中的关键技术包括虚拟环境建模、实时三维图像生成技术、交互技术、系统集成技术。随着虚拟现实技术的快速发展和广大园林景观设计者的积极参与,虚拟现实技术在园林景观设计上的应用必将带动园林设计方法论、园林设计本质的革新。

On Application of Virtual Reality Technology to Landscape Designing

The technology of virtual reality is an advanced computer user interface technology, which provides users with a variety of intuitive and natural real-time senses and interactive means in the aspects of vision, touch, taste,etc, thus realizing the most convenient user-computer interaction without any complicated keyboard operation and improving the efficiency of the whole system, virtual reality is basically characterized by immersion,interaction and imagination. The designer and the user can get the comprehensive result of survey and design when the virtual reality technology is applied to the landscape architecture designing. Furthermore, this technology can show the user or designer the total information on landscape space, enable the user or designer to do some long-distance on-line browsing and communicating,make computer-assisted designing and decision, and help the public participate. However, there are several key problems in application of virtual reality technology to landscape architecture designing, such as modeling of virtual environment, real-time 3D-image-generating technology, interactive technology and system integrating technology. With the rapid development of virtual reality technology and the active participation of the landscape architects, the application of the virtual reality technology to the landscape architectural designing will surely bring along the innovation of the methodology and essence of landscape architecture designing.
