Can you be more specific?

Hi David,
I got two routes as polylines as lists of coordinates such as: [13.072624,52.333508,13.763972,52.679616] [52.679616,13.763972,52.333508,13.072624]
I need to compare the direction of two polylines. To do so I thought to get the angle between them and return true (going in the same direction) if it is smaller 45°.
example of route comparison==> https://i.stack.imgur.com/LDczR.png
How can I match two routes (means their direction are same or not)

Note that a polyline is a sequence of edges, but your example is only a pair of vectors.
You can take the dot product of two vectors to get the angle between them. The r3.Vector
type has a Dot
method for that. See https://en.wikipedia.org/wiki/Dot_product for more detail.
