@AndersDeleuran interesting approach to Space Syntax by using the Medial Axis, in other threads, such as Old Town Roofs I read that people had difficulties with finding such a line. Looks like a clever solution =b
I have already established a full space syntax analysis of the site (I did the pixel version of a Visibility Graph Analysis 
).
Thanks @w.radaczynski I will give Megarachne a try, looks really convenient for what I want. I also like the clear documentation. I have two questions:
- Can I use the vertical distance between mesh edges as weights? That way, I could compute the path with the least vertical deviation. This would be useful for wheelchair paths, amongst others.
- For smoothing the shortest path, would it hurt the speed of the algorithm a lot if I add diagonals across the entire mesh (so create 4 triangles out of every square)? If it doesn’t that would make it easier to convert the path into a smooth curve.
