随着模拟的复杂性、准确性、维度和规模的不断增加,有必要朝着数据密集型科学发现的方向迈出一步。参数依赖模拟是这样一个数据密集型任务的一个例子:研究人员对模拟结果对一组输入参数的依赖性感兴趣,改变基本参数,并希望立即看到视觉环境中变化的效果。在这种情况下,交互式探索是不可能的,因为即使是对应于一个参数组合的单个模拟也需要很长的执行时间,并且可能感兴趣的参数组合的总数很大。在本文中,我们提出了一种方法,计算转向与预先计算的数据作为一种特殊形式的视觉科学探索。我们认为一个参数化的模拟作为一个多变量函数的几个参数。使用稀疏网格的技术,这使得有可能采样和压缩潜在的高维参数空间,并有效地将模拟数据和预先计算的数据的组合提供给转向过程,从而使用户能够交互式地探索高维模拟结果。
With the ever-increasing complexity, accuracy, dimensionality, and size of simulations, a step in the direction of data-intensive scientific discovery becomes necessary. Parameter-dependent simulations are an example of such a data-intensive tasks: The researcher, who is interested in the dependency of the simulation's result on a set of input parameters, changes essential parameters and wants to immediately see the effect of the changes in a visual environment. In this scenario, an interactive exploration is not possible due to the long execution time needed by even a single simulation corresponding to one parameter combination and the overall large number of parameter combinations which could be of interest. In this paper, we present a method for computational steering with pre-computed data as a particular form of visual scientific exploration. We consider a parametrized simulation as a multi-variate function in several parameters. Using the technique of sparse grids, this makes it possible to sample and compress potentially high-dimensional parameter spaces and to effciently deliver a combination of simulated and precomputed data to the steering process, thus enabling the user to interactively explore high-dimensional simulation results.
