sample_random: Generate a random sample of points on the unit sphere

In cda: Coupled-Dipole Approximation for Electromagnetic Scattering by Three-Dimensional Clusters of Sub-Wavelength Particles

Description

Random sample

Random sample with minimum exlusion zone ("hard-core process")

Fibonacci coverage of a sphere

Usage

sample_random(N)

sample_hc(N, exclusion = 0.1, maxiter = 200L, k = 30L)

sample_fibonacci(N = 301)

Arguments

N	number of points
exclusion	minimum distance allowed between points
maxiter	maximum number of iterations
k	number of extra new points to try at each iteration

Details

Produces a set of points that covers rather uniformly the unit sphere with N points with a spiral-like pattern based on a Fibonacci sequence

Value

3xN matrix

3xN matrix
