Visibility3d -  list of ranges [from,to] - which nodes are visible from the current one. from, to are both relative to the current node, so merging several segments should not break visibility (not so easy in the map that is not linear path, but we'll think of something  - adding new nodes (importing KML) should not change the relative sequence of indices (kml "name" tag).
