基于GPU的十亿点宇宙学模拟交互式可视化

GPU-Based Interactive Visualization of Billion Point Cosmological Simulations

Tamas Szalay, Volker Springel, Gerard Lemson

摘要:

尽管最近在图形硬件能力方面取得了进步,但强力方法无法交互地显示TB级的数据。我们已经实现了一个系统,该系统对宇宙学模拟的结果使用分层的详细级别,以便在不加载完整数据集(包含超过100亿个点)的情况下显示视觉上准确的结果。该程序的指导原则是,用户不应该能够区分他们所看到的原始数据的完整渲染。此外,通过使用基于树的详细级别系统,底层数据的大小仅受包含它的IO系统的容量限制。

英文摘要:

Despite the recent advances in graphics hardware capabilities, a brute force approach is incapable of interactively displaying terabytes of data. We have implemented a system that uses hierarchical level-of-detailing for the results of cosmological simulations, in order to display visually accurate results without loading in the full dataset (containing over 10 billion points). The guiding principle of the program is that the user should not be able to distinguish what they are seeing from a full rendering of the original data. Furthermore, by using a tree-based system for levels of detail, the size of the underlying data is limited only by the capacity of the IO system containing it.
