声景观虚拟仿真资产管理——以SketchUp平台作为中间件

SketchUp platform as the middleware-A Method of Asset Management for Sounds-cape Simulation in the Game Engine Environment

以虚幻引擎中的声景观重建技术作为背景,着眼于声景观虚拟建模前期的工具优化,笔者提出了将SketchUp软件平台作为声景观资产管理的中间件,以此辅助声景观素材快速采集与重建流程中的信息管理。在分析虚拟声景观建模的工作流程的基础上,提出了利用SketchUp记录话筒空间信息的技术方案,重点探索了SketchUp平台基于IFC分类的对象属性拓展方法,为今后声景观建模的中间件开发提供了比较成熟的技术路线。

Based on the technical background of soundscape reproduction in Unreal Engine,this paper describes the improvement of the software tool utilized in soundscape research and data collecting.The 3D modelling platform SketchUp is selected to be the mid-dleware that bridges the rapid data collecting in-situ and data management in the model reproduction.A brief workflow for sounds-cape reproduction in the virtual environment is summarized.Then significant applications of the SketchUp platform are introduced to log spatial information of the microphone.Finally,this article concentrates on the methods to extend the attributes in the SketchUp platform based on IFC classification,providing a promising technical route for further development of the middleware of soundscape asset management.
