Visualization of datasets stemming from diverse sources is challenged by the large variety of substantial differences in topology, geometry and nature of the associated data fields. Since there is no standard on how to formulate and treat data for scientific visualization, algorithms are frequently implemented in a highly domain-specific way. Here, we explore the potential of point-wise rendering as a generic way to represent single or multiple fields instantaneously on arbitrary mesh types. This approach is discussed within the terminology of fiber bundles as a general mathematical concept to model scalar-, vector- and tensorfields given on topological spaces (with manifolds as a particular case). We give application examples based on datasets originating from astrophysics and show first results of a tensor field visualization of a recently produced complex dataset of colliding black holes in their final orbit. We finally propose a data layout representing the mathematical concept of a 'field' generic enough to handle all cases involved.
