This document discusses interactive simulation and visualization of large-scale flooding scenarios. It covers topics such as real-time 3D visualization of massive LiDAR point clouds, interactive adaptive simulation of flooding scenarios, and multi-scenario comparative simulation visualization. The goal is to develop techniques to simulate and visualize different flooding scenarios and uncertainties to help decision makers and the general public understand the risks and impacts of potential flooding events.
