RIA: Realistic Interactive Visualization for Computational Fluid Dynamics

9409243计算流体动力学(CFD)模拟的埃伯特可视化是计算流体力学研究人员的重要工具。然而，目前的可视化系统在几个方面都缺乏。首先，许多系统不能显示数据中包含的所有三维信息，只显示流线、等高线或等值面。其次，大多数系统只是一个后处理步骤，不能并入计算模型的开发周期。第三，大多数系统不允许以易于理解的格式同时显示多个流量变量。该项目将开发一个交互式曲面和体积可视化系统，用于CFD模拟的三维可视化。该系统将使用逼真的气体和流体的体积绘制技术来显示CFD模拟的完整三维数据，包括同时显示多个流动变量。将使用三维感知辅助工具，如准确的阴影、大气衰减和折射，以增加数据的可理解性。此外，该系统将允许研究人员可视化和交互地更改他们的模型，帮助调试计算模型，减少CFD模拟的开发时间。这一新系统可以用作交互式虚拟风洞。***

9409243 Ebert Visualization of computational fluid dynamics (CFD) simulations is an important tool for CFD researchers. However, current visualization systems are lacking in several ways. First, many systems fail to display all of the three-dimensional information contained in the data, only displaying stream-lines, contour plots, or isosurfaces. Second, most systems are a post- processing step only and cannot be incorporated into the development cycle for the computational model. Third, most systems do not allow multiple flow variables to be displayed simultaneously in an easily understandable format. This project will develop an interactive surface and volumetric visualization system for the three-dimensional visualization of CFD simulations. This system will use realistic volume rendering techniques for gases and fluids to display the complete three- dimensional data from the CFD simulation, including the simultaneous display of multiple flow variables. Three- dimensional perception aids, such as accurate shadows, atmospheric attenuation, and refraction, will be used to increase the understandability of the data. Furthermore, the system will allow researchers to visualize and to change their models interactively, aiding in the debugging of the computational models and decreasing the development time of the CFD simulation. This new system can be used as an interactive virtual wind tunnel. ***
