基于UE4引擎的室内虚拟交互设计的研究

Research on virtual interaction design for interior based on UE4 engine

针对室内设计中效果方案缺乏用户与室内场景交互的情况,对室内虚拟场景内的交互功能和实现方式进行了研究,对制作基于虚幻引擎平台的室内虚拟交互系统进行了实践。系统主要基于Unreal Engine4引擎完成,使用Auto CAD完成室内场景数据采集的汇总,在3ds MAX中进行三维模型创建与材质编号,在UE4中进行材质纹理设置、交互蓝图编程、物理碰撞等测试。方案具备了设计效果与毛坯房场景切换、自主空间漫游、界面及材质替换等交互功能,能够实现用户在电脑端或VR设备端进行空间体验的可视化程序。室内虚拟场景的设计能够呈现具有真实性的室内空间,切实帮助设计师进行设计方案的表达,为用户带来空间尺度和造型设计上的直观感受,也为将虚拟现实技术应用于室内设计领域的研究提供了思路。

In response to the lack of user interaction with the interior scene in the effect scheme of interior design,the interactive functions and implementation methods within the interior virtual scene were studied,and an interior virtual interactive system based on the Unreal Engine platform was produced for practice.The system was mainly based on the Unreal Engine4 engine,using Auto CAD to complete the summary of indoor scene data collection,3ds MAX to create 3D models and material numbering,material texture settings in UE4,interactive blueprint programming,physical collision and other tests,with design effects and rough room scene switching,independent space roaming,interface and material replacement and other interactive functions to realise the visualization process of the user's spatial experience on the computer side or VR devices.The design of interior virtual scenes can present interior spaces with realism,practically help designers to express their design solutions,bring users an intuitive feeling of spatial scale and design modeling,and also provide ideas for applying virtual reality technology to research in the field of interior design.
