Creates visually even spacing of n points on the surface of the sphere. Nearest-neighbor 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"` .
