Abstract:
We present an alternative method for viewing time-varying volumetric
data. We consider such data as a four-dimensional data field, rather than
considering space and time as separate entities. If we treat the data in
this manner, we can apply high dimensional slicing and projection
techniques to generate an image hyperplane. The user is provided with an
intuitive user interface to specify arbitrary hyperplanes in 4D, which can
be displayed with standard volume rendering techniques. From the volume
specification, we are able to extract arbitrary hyperslices, combine
slices together into a hyperprojection volume, or apply a 4D raycasting
method to generate the same results. In combination with appropriate
integration operators and transfer functions, we are able to extract and
present different space-time features to the user.
