vtk
視覺化工具函式庫（VTK，Visualization Toolkit）是一個開放源碼，跨平臺、支援平行處理（VTK曾用于處理大小近乎1個Petabyte的資料，其平臺為美國Los Alamos國家實驗室所有的具1024個處理器之大型系統）的圖形應用函式庫。2005年實曾被美國陸軍研究實驗室用于即時模擬俄羅斯制反導彈戰車ZSU23-4受到平面波攻擊的情形，其計算節點高達2.5兆個之多。
介紹及使用： http://www.cnblogs.com/buffer/archive/2009/03/13/1410235.html結合Qt使用，部分代碼示例（線圖）：（\vtk-5.6.1\GUISupport\Qt\Testing\CxxTestLineSeries.cxx）
