Idea for adding a custom cost function to the fmm

[ziXet]

Hi,

I know that the implementation of the UBODT algorithm is using dijkstra algorithm for finding the "shortest" path.

If I want to implement a custom cost function as simple as a taking the type of the edge into the consideration.

Example (Now):
cost = distance

Example (New)
cost = distance1.5 -> for "service" road
cost = distance1.1 -> for "highway" road

I just want to know if this is possible and if "Yes" what part of the cpp code needs to be changed.

Thanks
