针对散乱点数据，构建出三角网，并追踪出等值线，随后进行填充算法实现。附件中包含有实现源代码工程（VS2008）、编程调试文档笔记、试验数据等。-For scattered point data, construct a triangle mesh, and track the contour, followed by filling algorithm. Implementation annex contains the source code project (VS2008), programming and debugging, documentation notes, test data.
