Ricksep is a freely-available interactive viewer for multi-dimensional cubes, capable of simultaneous display of multiple data sets from different viewing angles, animation of movement through the data space, and selection of local regions for data processing and information extraction. Several new features are added to Ricksep to enhance the program's functionality. First, two new data-fusion algorithms synthesize a new data set from two source data sets, one with mostly high-frequency content, such as seismic data, and the other with mostly low-frequency content, such as velocity data. Previously separated high and low-frequency details can now be viewed together. Second, a new projection algorithm, integrated with Ricksep's point-picking capabilities, effectively displays arbitrary paths through the data space. The algorithm responds to path changes in real time, restores depth information lost through ordinary projection techniques, and supports the generation of multiple paths differentiated by point-picking symbols. Third, a viewing history list is maintained to enable Ricksep's users to edit and save a sequence of viewing states. The feature supports undoing and redoing of viewing commands and animation of viewing sequences, a generalization of the viewer's movie feature. A theoretical discussion and several examples using real seismic data show how the new features offer more convenient, accurate ways to manipulate multi-dimensional data sets.
