The visual analysis of multifield data is one of the big research challenges in the field of Scientific Visualization. In recent years, many approaches for this have been proposed which either do a side-by-side visualization if the fields or apply semi-automatic methods to compute and visualize the relations between the fields. However, most existing techniques focus on multifields of the same type, for instance a collection of multiple scalar fields. Recent multifields tend to consist of fields of different types, i.e., scalar, vector andtensor fields are acquired over the same domain. This project proposes approaches for the visualization of multifields of different types. In particular, we propose similarity measures between multitype fields, we define features describing the correlations between multitype fields, and we adapt discrete methods from Information Visualization for multitype fields. The approaches are tested and evaluated on a number of test data sets from different areas of application.

多场数据的视觉分析是科学可视化领域中最大的研究挑战之一。近年来，已经提出了许多方法，如果字段或应用半自动方法来计算和可视化磁场之间的关系，则可以进行并排可视化。但是，大多数现有技术都集中在同一类型的多场上，例如多个标量字段的集合。最近的多场倾向于由不同类型的字段组成，即标量，向量和tensor场是在同一域上获得的。该项目提出了可视化不同类型的多场的方法。特别是，我们提出了多元字段之间的相似性度量，我们定义了描述MultyPe字段之间相关性的功能，并且我们从Muttonpe字段的信息可视化中调整了离散方法。对来自不同应用领域的许多测试数据集进行了测试和评估。
