ComputeGoldenSpiralPoints(TArray< TVec3< T > > &, const TVec3< T > &, const T, const int32, const bool, const bool, const int32)

Description

Use the golden spiral method to evenly distribute points on a sphere.

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 sphere, ending at the top. Contiguous entries in `Points_ generally will not be spatially adjacent.

Points_ to append to. Center_ is the center of the sphere. Radius_ is the radius of the sphere. NumPoints_ is the number of points to generate. BottomHalf_ causes the bottom half of the sphere to be generated, starting at Center_ - (0, 0, Radius_). TopHalf_ causes the top half of the sphere to be generated, starting at Center_. 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.
