Application breaks when using segmentation tool about volume-cartographer HOT 5 CLOSED

Great, thanks!

I think the segmentation algorithm throws an exception if a point goes out of the volume bounds. On slice 0, the point doesn't have to go very far to be considered OOBs, so that's probably what's happening here, and we're not catching/handling the exception.

Given you got a different segmentation to work on slice zero (and so did we for the tutorial), it's probably conditional on the exact pointset used.

A good workaround is to go a few slices in and start from there. You don't lose much by doing that. If you go one slice in, you lose about one row of pixels from the final 2D result.

Thanks for giving me your segmentations. It helped me fix a number of potential bugs. One thing I hadn't seen before is that your segmentation had adjacent, duplicate points:

This was causing some backend curve interpolation code to create a point outside of the volume, which lead to an uncaught exception, which crashed the program.

I've done a number of things in #8 to fix all of these compounded issues. Thanks again for reporting!

Try making a new segmentation on slice 1 instead of 0 and let me know what happens.

EDIT: Oh, and please zip up the segmentation directory inside *.volpkg/paths/ and send that to me so I can test a fix.

I switch to slice 1 and do it again and it works well. So I come back to slice 0 to do another new segmentation again and it works as well. The following is the path folder:

20230318015423: slice0 (not work)
20230318042534: slice1 (work)
20230318042733: slice0 (work)

Glad to know my segmentations data can help. Great work & thanks for the quick fix.
