摘　　要：三维建模技术在各个领域发挥着重要作用,但以桌面交互为主的三维建模方式仍复杂、抽象且不支持在线协作。为此,借助虚拟现实(VR)技术的沉浸性、交互性、想象性等优点,提出一种VR环境下的网络协同三维建模方法,使得用户以沉浸式的交互方式建立三维模型,并支持多人实时在线可视化协作。首先,提出了一种VR环境下的三维模型绘制交互方式;其次,将三维模型进行分类,提出一种分层构建式的三维模型网格生成算法,用于建立平面模型和立体模型;最后,设计了一种VR环境下的三维建模网络协同模块,并基于Socket通信实现了网络同步。通过与传统三维建模软件的三维建模方法进行对比实验表明,该方法更加简捷、直观和高效,且易于普通用户掌握。,and lacks support for online collaboration.Therefore,utilizing the advantages of immersion,interaction,and imagination of virtual reality(VR)technology,a network collaborative 3D modeling method in a VR environment was proposed.This method enabled users to create 3D models through immersive interaction and supported multi-user real-time online visual collaboration.Firstly,a 3D model drawing interaction method in a VR environment was proposed.Secondly,the 3D models were categorized,and a 3D model mesh generation algorithm based on Layered Build was proposed for building planar models and 3D models.Finally,a 3D modeling network collaboration module in a VR environment was designed,achieving network synchronization through Socket communication.Comparative experiments with the 3D modeling methods of traditional 3D modeling software demonstrated that this method is more concise,intuitive,and efficient,making it easy for ordinary users to master.
