Description

Use the golden spiral method to generate evenly spaced points on a tapered capsule (truncated cone with two hemispherical ends).

The "golden" part is derived from the golden ratio; stand at the center, turn a golden ratio of whole turns, then emit a point in that direction.

Points are generated starting from the bottom of the tapered capsule part, ending at the top. Contiguous entries in `Points_ generally will not be spatially adjacent.

Points_ to append to. Origin_ is the bottom-most point of the tapered capsule. Axis_ is the orientation of the tapered capsule. Radius1 is the first radius of the tapered capsule. Radius2_ is the second radius of the tapered capsule. Height is the height of the tapered capsule. NumPoints_ is the number of points to generate. SpiralSeed_ is the starting index for golden spiral generation. When using this method to continue a spiral started elsewhere, `SpiralSeed_ should equal the number of particles already created.
