Helper functions for dealing with 2D polylines. A polyline is just a vector of 2D (x y) vectors.
Example: A polyline with 4 vertices.

lengthclj/s
(length polyline)Returns the length of a polyline.
Returns the length of a polyline.
lengthsclj/s
(lengths polyline)Returns the lengths between each vertex of a polyline. The size of the output is N-1.
Returns the lengths between each vertex of a polyline. The size of the output is N-1.
lerpclj/s
(lerp polyline t)Returns a point on the polyline at t (float between 0-1).
Returns a point on the polyline at t (float between 0-1).
normalsclj/s
(normals polyline)Returns the normals of each vertex in the polyline.
Returns the normals of each vertex in the polyline.
resample-by-countclj/s
(resample-by-count polyline n)Resamples the polyline evenly
Resamples the polyline evenly
resample-by-lengthclj/s
(resample-by-length polyline len)Resamples the polyline by a length
Resamples the polyline by a length
scaleclj/s
(scale n start1 stop1 start2 stop2)scales a number to a new range
scales a number to a new range
smoothclj/s
(smooth polyline size & closed)Returns a smoothed polyline. The size indicates how many verices to the left and right of each vertex to take when smoothing. This is a basic rolling average of a line. Optional third argument indicates if line is wrapped.
