我们推出了 Submerse，这是一个端到端框架，用于在大型沉浸式显示生态系统中可视化洪水场景。具体来说，我们根据输入的洪水模拟数据重建表面网格，并通过合并地形、纹理、建筑物和其他场景对象等地理数据来生成按比例缩放的 3D 虚拟场景。为了优化大型模拟数据集的计算和内存性能，我们使用动态四叉树在自适应网格上离散化数据，并支持基于细节级别的渲染。此外，为了提供对某个时间实例的洪水方向的感知，我们通过合成水波对表面网格进行动画处理。由于交互是有效决策和分析的关键，我们引入了沉浸式系统中洪水可视化的两种新技术：（1）一种自动场景导航方法，使用根据显示布局为标记的兴趣点生成的最佳摄像机视点；（2）一种使用辅助显示系统的基于 AR 的焦点+上下文技术。 Submerse 是计算机科学家和大气科学家合作开发的。我们通过在 Stony Brook Reality Deck（一个沉浸式十亿像素设施）中与应急管理人员、领域专家和相关利益相关者举办研讨会来评估我们系统和应用程序的有效性，以可视化纽约市的超级风暴洪水场景。
We presentSubmerse, an end-to-end framework for visualizing flooding scenarios on large and immersive display ecologies. Specifically, we reconstruct a surface mesh from input flood simulation data and generate a to-scale 3D virtual scene by incorporating geographical data such as terrain, textures, buildings, and additional scene objects. To optimize computation and memory performance for large simulation datasets, we discretize the data on an adaptive grid using dynamic quadtrees and support level-of-detail based rendering. Moreover, to provide a perception of flooding direction for a time instance, we animate the surface mesh by synthesizing water waves. As interaction is key for effective decision-making and analysis, we introduce two novel techniques for flood visualization in immersive systems: (1) an automatic scene-navigation method using optimal camera viewpoints generated for marked points-of-interest based on the display layout, and (2) an AR-based focus+context technique using an aux display system. Submerse is developed in collaboration between computer scientists and atmospheric scientists. We evaluate the effectiveness of our system and application by conducting workshops with emergency managers, domain experts, and concerned stakeholders in the Stony Brook Reality Deck, an immersive gigapixel facility, to visualize a superstorm flooding scenario in New York City.
