Decreasing Segmentation Performance
Posted: Wed Dec 16, 2015 4:00 pm
I do a lot of Segment->Process->Merge operations, which I expect everyone does.
I've found that as I progress, more noticeably with larger clouds (100M+), the response of CC while drawing segmentation contours and performing the actual segmentation decreases. For example, creating a 20 vertex segmentation area in a 30M point cloud is instantaneous and performing the segmentation takes about 3 seconds at the beginning of a session. A few hours later I might have to wait 10 seconds to even see the results from clicking a segmentation point and I can make lunch while waiting for the segmentation to happen.
Of course I can always save my work to disk and restart CC but I may have 20 clouds segmented out of the original by that time.
On a related note, occasionally the toolbar doesn't come back after a segmentation completes and is waiting for you to click the check or the X. Clicking on the title bar of the CC window brings it back.
