3D visual design of outdoor interactive space landscape based on GML

构建空间景观三维模型是实现户外交互空间景观三维可视化的有效途径,针对当前户外空间景观三维数据模型不容易统一,难以有效完成空间景观的三维可视化共享与交互过程等问题,提出基于GML的户外交互空间景观三维可视化模型构建方法。对户外交互空间景观的多源异构数据进行集成处理,将其转换为标准的GML格式;从GML空间景观数据中选择合适的三维特征,并据此对户外空间景观数据进行分类;根据空间景观对应的三维特征,利用三维建模软件完成空间景观三维模型构建,实现户外交互空间景观三维可视化。实验结果表明,本文方法能够有效地完成户外空间景观三维可视化建模,且整个建模过程耗时更短。

Constructing a three-dimensional model of the spatial landscape is an effective way to realize the three-dimensional visualization of the outdoor interactive spatial landscape.In view of the fact that the current outdoor spatial landscape three-dimensional data model is not easy to unify and it is difficult to effectively complete the three-dimensional visualization sharing and interaction process of the spatial landscape.A 3D visualization model construction method of outdoor interactive space landscape based on GML was proposed.Integrate multi-source heterogeneous data of outdoor interactive spatial landscape and convert it to standard GML format;select appropriate three-dimensional features from GML spatial landscape data,and classify outdoor spatial landscape data accordingly;according to spatial landscape corresponding three-dimensional features,the use of three-dimensional modeling software to complete the construction of the three-dimensional model of the spatial landscape,to achieve three-dimensional visualization of outdoor interactive spatial landscape.Experimental results show that the proposed method can effectively complete the three-dimensional visual modeling of outdoor space landscape,and the entire modeling process takes less time.
