三维园林植被景观构建与虚拟展示
|
摘要
绿地系统具有生态、文化、社会和审美的多重功能,由于植物形态结构复杂多样,城市规划中尚未有系统、定量化的设计。利用虚拟现实、虚拟植物和地理信息系统等新技术,提出了参数化虚拟植被景观规划设计和虚拟展示的概念模型,集成了参数化植物建模方法和植物空间布局方法。结合园林绿地实例,根据参数化植物建模方法,获取绿化植物形态结构参数,建立各种植物造型的三维模型;采用参数化描述植物空间布局的规则,基于Open Scene Graph(OSG)图形渲染引擎,集成Oculus rift虚拟现实设备,实现三维园林植被景观的虚拟构建及展示。以某大学为例,验证了整体方案的有效性。
Green space system has multifunction like ecology, culture, society and aesthetic. Meanwhile, because of the complicated plant morphological structure, there is no systematic and quantified design in urban planning. Via Virtual Reality(VR), Virtual Plants(VP)and GIS technologies etc., therefore, parametric VP landscape design and concept model in virtual exhibition have been proposed, and the parametric plant modeling method is combined with the plant spatial layout. With the help of the garden landscaping example, the parametric modeling method approach and the plant morphological structure parameters to build the three-dimensional model of garden vegetation. Then, the plant spatial layout rules are described through parameterization. On the basis of Open Scene Graph(OSG), Oculus rift VR outfit is integrated, and the three-dimensional models' construction and virtual exhibition have been realized. Afterwards, taking Fuzhou University as example, has verified that the overall solution is effective.
