Summary0000410: slices at arbitrary orientations may not travel the entire volume
Description

This one is a little hard to pin down, I'll try to make it clear.

I don't have a single reproducible case, but believe it is the same on any volume.

If you take a slice and rotate it's orientation off the primary axes, you may no longer be able to reach all of the volume with it. In other words, both the slider and numerically setting the slice offset will be constrained to a subvolume. This is particularly noticeable with large rotations, but also it seems to matter which position you start in, and which direction(s) you rotate it in.

I'll try and play with this a bit to narrow down the behaviour. Perhaps I can provide a .mrml file exhibiting the problem, but it would have to include a data volume.

This report a bit rushed, sorry, I'll try and clean up later.

Additional Information

Fixed computation of slice bounds for a rotated slice. Seems to work now.

Simon, could you verify the fix?

I suspect this is related/equivalent to 0000129

129 is fixed now, please reopen this if it is still a problem.

I thought this might duplicate 129, but it does not so reopening.

[...]

contains a data file and .mrml.

I opened the data, set yellow slice to reformat, rotated (with Ctrl-mouse) counterclockwise to the saved position.

As loaded in version 8701, this slice will not travel through it's range.

Please advise when you've downloaded the example.

by the way, using arrow keys to get around this seems to (sometimes?) only work in one direction. If I have a chance, I'll see if that's consistent.

Okay, yes, I see now. I downloaded the example and can replicate this with any volume once I rotate the slice plane a little.

It looks like this change handles the case of a rotated volume, but not a rotated slice plane.

there is added discussion of this bug on slicer-devel. It wasn't immediately obvious it was the same bug, but it turns out to be another way of triggering it (by rotating the planes).

I'll have a look at the above diff and see if it provides a clue how to fix this one.
