known bugs:
- bad work with the outer side of the arc

k = (B.y - A.y)/(B.x - A.x);


k = 0 when A.y == B.y
if (A.y == B.y) then x = C.x; y = A.y; break; end

k = inf when A.x == B.x
if (A.x == B.x) then x = A.x; y = C.y; break; end

Quote from repeat83 :

k = (B.y - A.y)/(B.x - A.x);


k = 0 when A.y == B.y
if (A.y == B.y) then x = C.x; y = A.y; break; end

k = inf when A.x == B.x
if (A.x == B.x) then x = A.x; y = C.y; break; end

thanks

Well, I'm officially impressed and jealous that you figured that out.

Well.. It's also quite some work to create that json with road coordinates?

if i understand it right:
about 10 hours to write system and 2 hours for content

Interessting. The road coordinates are done by hand or generated somehow from pathfiles or smx meshes?
Sometimes there was some bugs, see attached picture. (maybe you already know)

done by hand.
about bugs i know =)
