vtk
视觉化工具函式库（VTK，Visualization Toolkit）是一个开放源码，跨平台、支援平行处理（VTK曾用于处理大小近乎1个Petabyte的资料，其平台为美国Los Alamos国家实验室所有的具1024个处理器之大型系统）的图形应用函式库。2005年实曾被美国陆军研究实验室用于即时模拟俄罗斯制反导弹战车ZSU23-4受到平面波攻击的情形，其计算节点高达2.5兆个之多。
介绍及使用： http://www.cnblogs.com/buffer/archive/2009/03/13/1410235.html结合Qt使用，部分代码示例（线图）：（\vtk-5.6.1\GUISupport\Qt\Testing\CxxTestLineSeries.cxx）
