The tool allows you to set the quality of the model both in dynamic and static state.
The opacity threshold allows to ignore relatively transparent tissue when performing measurements and creating segments. That is, the tissue whose transparency level is below a predetermined value will be visible, but the points of the measuring tools will be projected on the tissue with a higher level of transparency. Such tissue will not be included in the segment.
To set quality:
If the quality is high, the update image may be delayed because of low computer resources.
