This is a difficult problem, but I have a plan to deal with it in
LOCI's "4D Data Browser" plugin
(
http://www.loci.wisc.edu/ome/browser.html), which has similar
functionality to the Virtual Stack Opener.
The plan is to automatically record operations the user performs as
macro commands, similar to how the Macro Recorder shows them. Then,
when a new slice is loaded from disk, transparently apply the recorded
macro to the new slice. Further operations continue to be recorded and
are appended to this "automatic" macro. From the user's perspective,
it will seem as though everything is working normally, at least for
fast operations. For slower ones, there will be a decrease in
performance as new slices are loaded from disk.
Unfortunately, I have not had time to thoroughly implement this idea
yet, and cannot say when I will be able to do so. But a future version
of the 4D Data Browser will have some way of dealing with this
problem.
If anyone has any further thoughts or comments on this idea, I welcome them.
