Having two linestrings, one with overview path, which uses less points and draws incomplete line - Overview path. And then a detailed one where it loads a lot of points for correct route simulation.
I'm thinking of optimizing it with a deeper level, so it would show detailed line after certain zoom level for the distance of screen point A - B.
So theoretically I would need to get points where line and monitor connects and then redraw line so It would draw only from x to y.
Hare is what roughly the question is up for.
I would think this is useful for everyone, and it would be a big optimization issue solved. Unless it all ready have been and something floats around.
An issue with this would be a method to figure out how to locate the A B points of the detailed path. How ever it would be possible, to check which point comes closest to overview path that is outside view port.
