Hi Cvetan,

Well done on the update. I'm curious, are you using a grid based routing algorithm or a modified isochrone algorithm? I've been coding some stuff for OpenCPN and I'm struggling with land obstruction.
Thanks

Cags

It's a polar grid with point sifting based on a "further from start" goal function that leaves only limited number of points in each angular sector in order to avoid exponential complexity.


Land obstruction is tough to solve properly. Most of the time it does not really matter as long as the track will fix itself as soon as you get past the obstruction, but it's hard to get proper "around the corner" track right from the start.
