In this article, an entirely parallel pipeline for creating realistic visualization of particle-based fluid is presented, which significantly improves surface reconstruction and foam generation performance. Firstly, we develop a spatial hashing grid-based strategy. Based on this strategy, a novel narrow band surface reconstruction method is presented, which could even discard the detection of surface particles methods to achieve the effect of accurate identification of surface vertices. And a novel narrow band like diffuse particle classification method is proposed, which ensures less memory access and less computation. Furthermore, in order to obtain a best performance, we put forward several parallel schemes to avoid potential race conditions and invalid threads. Experiments are conducted to verify that our developed method and code efficiently improve the particle-based visualization.

基于粒子的流体的并行逼真可视化
在本文中，提出了一种用于创建基于粒子的流体的逼真可视化的完全并行的管道，它显着提高了表面重建和泡沫生成性能。首先，我们开发了一种基于空间散列网格的策略。基于该策略，提出了一种新颖的窄带表面重建方法，该方法甚至可以摒弃表面粒子的检测方法，达到对表面顶点进行准确识别的效果。并提出了一种新颖的窄带扩散粒子分类方法，确保更少的内存访问和更少的计算。此外，为了获得最佳性能，我们提出了几种并行方案来避免潜在的竞争条件和无效线程。
