In many application areas, decisions can only be made by exploring alternative scenarios. The goal of the suggested approach is to support users in this decision making process. In this setting, the data domain is extended to a set of alternative worlds where only one outcome will actually happen. World Lines integrates simulation, visualization and computational steering into a single unified system that is capable of dealing with the extended solution space. World Lines represents simulation runs as causally connected tracks that share a common time axis. This setup enables users to interfere and add new information quickly. A World Line is introduced as a visual combination of user events and their effects in order to present a possible future. To quickly find the most attractive outcome, we suggest World Lines as the governing component in a system of multiple linked views and a simulation component. World Lines employs linking and brushing to enable comparative visual analysis of multiple simulations in linked views. Analysis results can be mapped to various visual variables that World Lines provides in order to highlight the most compelling solutions. To demonstrate this technique we present a flooding scenario and show the usefulness of the integrated approach to support informed decision making.", month = nov, journal = "IEEE Transactions on visualization and Computer Graphics", number = "6", volume = "16", booktitle = "IEEE Transactions on Visualization and Computer Graphics", pages = "1458--1467", keywords = "decision making, simulation steering, parallel worlds, CFD, smoothed particle hydrodynamics., Problem solving environment", URL = "https://www.cg.tuwien.ac.at/research/publications/2010/Waser-2010-WL/", } @mastersthesis{Ribicic-2010-CRS, title = "COMPARATIVE RENDERING OF SIMULATION SCENARIOS", author = "Hrvoje Ribi\v{c}i\'{c}", year = "2010", abstract = "In the course of this thesis, a software solution that can be used to handle the simulation and visualization of multiple flooding scenarios was developed. Multiple alternatives can be simulated at once, and the user can jump between various simulation states and explore them at will. New alternatives can be explored by changing parameters or introducing events into the simulation. The thesis is centered around the study of breach-closure procedures used to repair the damage done to the levees of New Orleans after hurricane Katrina. A simulation scenario resembling the original study was made and used to explore alternative ways of closing the breach. The results of the simulation are rendered to the user using the screen-space fluid with curvature-flow rendering-method. To allow ease of exploration, additional views that allow the user to compare simulation states were developed. These views show which buildings are threatened in various states, and the properties of the simulated fluid across multiple states. It is shown that these views follow a common approach that can be used to create new comparative renderings.", address = "Favoritenstrasse 9-11/E193-02, A-1040 Vienna, Austria", school = "Institute of Computer Graphics and Algorithms, Vienna University of Technology ", keywords = "visualization, comparative rendering, SPH, Fluid simulation, fluid rendering, computational steering, World Lines", URL = "https://www.cg.tuwien.ac.at/research/publications/2010/Ribicic-2010-CRS/", }
