# vx_contour
|
|
|
|
|
|
|
|
|
|
Given a list of points that form a closed area, `vx_contour` returns the contour which encircles the area.
|
|
|
|
|
|
|
|
|
|
## Parameters
|
|
|
|
|
|
|
|
|
|
- `points` : A list of `[x, y]` points.
|
|
|
|
|
- `sorted` : Default to `false`. If your points is sorted by x y, setting it to `true` will accelerate the calculation speed.
