# vx_contour
|
|
|
|
Given a list of points that form a closed area, `vx_contour` returns the contour which encircles the area.
|
|
|
|
**Since:** 2.5
|
|
|
|
## 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);
|
|
}
|
|
}
|
|

color("black")

linear_extrude(1)
|
|
for(i = [0:len(t) - 1]) {
|
|
translate([i * 8, 0])
|
|
polygon(vx_contour(vx_ascii(t[i])));
