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.

多场数据的可视化分析是科学可视化领域的一大研究挑战。近年来，已经提出了许多方法，这些方法或者对场进行并行可视化，或者应用半自动方法来计算和可视化场之间的关系。然而，现有的大多数技术都集中在相同类型的多个字段上，例如多个标量字段的集合。最近的多场往往由不同类型的场组成，即在同一个域上获得标量场、矢量场和张量场。该项目提出了不同类型的多场可视化的方法。特别是，我们提出了多类型场之间的相似性度量，定义了描述多类型场之间相关性的特征，并将信息可视化中的离散方法应用于多类型场。这些方法在来自不同应用领域的多个测试数据集上进行了测试和评估。
