摘要:随着硬件和互联网技术以及BIM技术的发展，为了在业主、设计、建设等单位沟通更加高效便捷，构建一套完整的基于移动设备的建筑协同设计解决方案显得十分必要。本文主要介绍一种可以浏览建筑三维模型、查看项目说明文档、使用文本图片等方式反馈审批建议的移动应用。在移动设备服务于建筑协同设计的同时，其本身的有限内存带宽和CPU计算速度也限制着系统在显示大模型时的渲染速度。通过作者的学习和工作经验，本文主要从用户交互、显示优化和跨平台技术等方面进行探讨。

Abstract: In the last decades, the mobile devices had an astonishing growth rate and the smart phones became more and more popular throughout the world, it is significant to introduce more mobile applications into AEC industry in order to build an efficient way of communicating between owners, designers, constructors and other persons.This paper presents a mobile application which is designed to view architecture model, structure model or MEP model in 3D format, view project information and documentation and send feedback in text, image, sound or video format.While the transmission speed of the large-scale 3D-models in a limited band width is the major problem to be solved to satisfy the practical application requirements.Based on the authors' studying and development practice, the solutions were obtained which are presented in this paper, such as user interaction, display optimization technology and cross-platform technology.
