Abstract
This thesis presents an alternative method for viewing time-varying volumetric data. The data are considered as a four-dimensional data field, rather than considering the space and time axes as separate. If it is treated in this manner, we can apply high dimensional slicing and projection techniques to generate an image to study the data. The user is able to easily specify how to slice in space and time which implicitly specifies a 3D image hyperplane, e.g. a volume, that can be rendered with standard volume rendering techniques. From the user hyperplane specification, we are able to extract arbitrary hyperslices from 4D space. Additionally, we can project the hyperslices to a hyperprojection volume or apply a 4D raycasting method to generate the same results. In combination with different types of integration operators and transfer functions, the user is able to extract and study different spatio-temporal features.
