Description
Generates evenly spaced points on a cylinder, oriented about the Z axis, varying from [-Height/2, Height/2].
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 cylinder, ending at the top. Contiguous entries in `Points_ generally will not be spatially adjacent.
Points_ to append to. Radius_ is the radius of the cylinder. Height_ is the height of the cylinder. NumPoints_ is the number of points to generate. IncludeEndCaps_ determines whether or not points are generated on the end caps of the cylinder. 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.
