Returns shape points of a starburst. They can be used with xxx_extrude modules of dotSCAD. The shape points can be also used with the built-in polygon module.

## Parameters

`r1`

: The outer radius of the starburst.`r2`

: The inner radius of the starburst.`n`

: The number of vertices.

## Examples

```
include <shape_starburst.scad>;
polygon(shape_starburst(30, 12, 6));
```

```
include <shape_starburst.scad>;
include <circle_path.scad>;
include <rotate_p.scad>;
include <golden_spiral.scad>;
include <cross_sections.scad>;
include <polysections.scad>;
include <golden_spiral_extrude.scad>;
shape_pts = shape_starburst(5, 2, 8);
golden_spiral_extrude(
shape_pts,
from = 5,
to = 10,
point_distance = 1,
scale = 10
);
```
