# bauer_spiral
|
|
|
|
Creates visually even spacing of n points on the surface of the sphere. Successive points will all be approximately the same distance apart.
|
|
|
|
(It's called "visually even spacing" because only the vertices of the 5 [Platonic solids](https://en.wikipedia.org/wiki/Platonic_solid) can be said to be truly evenly spaced around the surface of a sphere.)
|
|
|
|
**Since:** 2.5
|
|
|
|
## Parameters
|
|
|
|
- `n` : The number of points.
|
|
- `radius` : The sphere radius. Default to 1.
|
|
- `rt_dir` : `"CT_CLK"` for counterclockwise. `"CLK"` for clockwise. The default value is `"CT_CLK"`.
|
|
|
|
## Examples
|
|
|
|
use <bauer_spiral.scad>;
|
|
use <polyline_join.scad>;
|
|
|
|
n = 200;
|
|
radius = 20;
|
|
pts = bauer_spiral(n, radius);
|
|
|
|
for(p = pts) {
|
|
translate(p)
|
|
sphere(1, $fn = 24);
|
|
}
|
|
|
|
polyline_join(pts)
|
|
sphere(.5);
|
|
|

You can use it to create [Text sphere](https://cults3d.com/en/3d-model/art/bauer-text-sphere).
