在 PDA 等移动设备上实现大型 3D 建筑模型的交互式可视化将极大地有益于室内导航器和移动旅游指南、建筑工地建筑设计的现场监控和注释、疏散培训和疏散指导等应用。
尽管 PDA 的功能越来越强大，有些甚至配备了 3D 硬件加速器，但它们的性能尚不允许以可接受的帧速率处理大型架构模型。为了面对这个问题，我们提出并实验了一个系统，该系统利用分层视锥体剔除和门户剔除在移动设备上交互式可视化 3D 建筑模型。我们还讨论了系统的性能及其与我们的移动 X3D 播放器 (MobiX3D) 的集成。该系统的性能已在一栋拥有 39 个房间、42 个楼梯和 42 个门的大型三层建筑上进行了评估。
Interactive visualization of large 3D architectural models on mobile devices such as PDAs would significantly benefit applications such as indoor navigators and mobile tourist guides, on-site monitoring and annotation of architectural designs at construction sites, evacuation training and evacuation guidance.
Although PDAs are becoming more powerful and a few are even equipped with 3D hardware accelerators, their performance does not yet allow to handle a large architectural model at an acceptable frame rate. To face this problem, we propose and experiment a system that exploits hierarchical view frustum culling and portal culling for interactively visualizing 3D architectural models on mobile devices. We also discuss the performance of the system and its integration with our mobile X3D player (MobiX3D). The performance of the system has been evaluated on a large three-floor building with 39 rooms, 42 stairs and 42 doors.
