在这篇论文中，我展示了如何在等值面场景中使用拓扑信息编码操纵单个轮廓表面，使用一个称为柔性等值面的接口。支撑这个接口的是对等高线树现有工作的几个改进和扩展。第一个，也是最关键的，扩展，是路径种子：一种新的方法，从等值面提取的轮廓树生成种子。第二个扩展是计算轮廓的几何信息，称为局部空间测量，并将此信息存储在轮廓树中。第三个扩展是使用局部空间测量来简化等高线树和等值面显示。这种简化也可以用于噪声去除。最后，本文将轮廓树的工作从单纯网格扩展到任意网格、插值和曲面细分的情况。
In this thesis, I show how to use the topological information encoded manipulation of individual contour surfaces in an isosurface scene, using an interface called the flexible isosurface. Underpinning this interface are several improvements and extensions to existing work on the contour tree. The first, and most critical, extension, is the path seed: a new method of generating seeds from the contour tree for isosurface extraction. The second extension is to compute geometric information called local spatial measures for contours and store this information in the contour tree. The third extension is to use local spatial measures to simplify both the contour tree and isosurface displays. This simplification can also be used for noise removal. Lastly, this thesis extends work with contour trees from simplicial meshes to arbitrary meshes, interpolants, and tessellation cases.
