adnanefouam commented 4 years ago

hello, thanks for bringing turf to dart ! is there will be Union function that Takes two or more polygons and returns a combined polygon ?

lukas-h commented 4 years ago

This library is work in progress. Feel free to make a pull request, since it is not yet implemented.

I have ported a libary that capable of doing all polygon Boolean operations on polygons (union, intersection, difference, xor) ( More info here

Hi @mohammedX6, this is really great! 😄 Do you want to create a pull request to make this part of turf_dart?

mohammedX6 commented 2 years ago

I don't think i have time to make pull requests but you can you use the libary dierftly without need of dart turf

lukas-h commented 8 months ago

closed because this is mostly implemented with the boolean* functions

lukas-h commented 8 months ago

what I wrote was not entirely correct. I did some test implementations of the difference function that is using @mohammedX6's poly_bool_dart lib. I don't like that we have to convert between our turf's Polygon and poly_bool's Polygon classes.

@mohammedX6 do you think we can use your library as a blueprint to implement the functionality as part of turf_dart without a dependency to your library?

I created a new issue for that: https://github.com/dartclub/turf_dart/issues/166
