In certain domains (e.g. dredging) the acquired data comes from single beam scanners, resulting in coordinates/points that represent a kind of cross sections of rivers, canals,... Those 'cross sections' aren't always straight. These 'non-straight' cross sections can create 'wrong' triangulations between the different sections (see screenshot below).
The following triangulation is expected for this type of terrain models:
The above result can be obtained by using the 'Swap Edge' editing command or by (manualy) creating longitudinal breaklines through each scanned point, but for this kind of projects it is enormly cumbersome and time-consuming.
Dreding companies work with surfaces with up to millions of points... For this kind of Customers (and certainly other users as well) it would be an enormous advantage and time-saver to have a tool where the direction of the triangulation could be forced in some kind of way. Or perhaps have the ability to swap edges in bulk (as the 'Minimize flat areas' command does for Contour line breaklines in case of flat triangles).
