摘　　要：随着众包成为大数据问题的流行解决方案,虚拟社区逐渐被应用到科学研究中,并借助手机交互,人们在追求高质量渲染的同时也开始探索渲染方法的普适性。本文研究一种蛋白质大分子三维可视化方法,该方法通过粒子系统管理大量原子,改进着色方法减少每个原子渲染时间,可以表达甘草和范德华模型,二级结构等常规表达。选取从103至105尺度的分子作为用例,与流行方法比较静止和交互时的效率,均具有更高效率,更适于移动平台。对分子结构进行域分解优化,进一步提高交互性能。成果发布至手机,可流畅运行。The crowd sourcing is becoming a popular solution to big data problems, and virtual community is gradually applied to scientific research. People also begin to pursue the high-quality rendering as well the universal rendering methods. This paper studies a protein macromolecules 3D visualization method, which is to manage the large number of atoms by the particle system, so as to reduce the rendering time of each atom by improving the coloration method, thus it can express Licorice and Van der Waals model, the secondary structure and some other conventional expressions. Taking molecules from the 103 tol05 scale as application examples, comparison of the static and interactive efficiency between the particle system method and the popular method shows that the former has better performances in both aspects. The domain decomposition of the molecular structure is optimized, and the interactive performance is improved apparently. The results can run smoothly when being published to the iPhone
