+# 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.)
+
+## 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 <hull_polyline3d.scad>;
+
+    n = 200;
+    radius = 20;
+    pts = bauer_spiral(n, radius);
+
+    for(p = pts) {
+        translate(p)
+            sphere(1, $fn = 24);
+    }
+
+    hull_polyline3d(pts, 1);

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