The several new features added to Ricksep are effective aids in data-fusion of volumes, visualization of paths, and revision of viewing sequences. Velocity View provides an accurate, convenient method of visually correlating localized structures and large-scale patterns. Path View enables clear visualization of paths that were previously invisible. History List provides for automation of viewing commands by saving the viewing history in an editable list. Moreover, all three features have simple interfaces and work in conjunction with the viewer's previous capabilities.
There is a good foundation on which to build future improvements to Ricksep. For Velocity View, the interface can be changed to allow multiple data-fusions to occur simultaneously. For example, if there are two pairs of high and low-frequency volumes, the two synthesized cubes can both be shown in the same window.
For Path View, as a generalization of creating paths from picks, entire surfaces can be generated from picks. The mathematics of multi-dimensional interpolating is not significantly more difficult than the mathematics of one-dimensional interpolation, but implementing this functionality in Ricksep is nontrivial.
For History List, other than the message bar informing users of the current position in the list, there is no other information about previous and following viewing states. A better interface would include a preview pane that includes information about viewing states before and after the current state.
