# 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.
## Examples
use <voxel/vx_ascii.scad>;
use <voxel/vx_contour.scad>;
t = "dotSCAD";
color("white")
linear_extrude(2)
for(i = [0:len(t) - 1]) {
translate([i * 8, 0])

for(pt = vx_ascii(t[i])) {
translate(pt)
square(1, center = true);
}
