Random Points on a Sphere (Generating Random Sequences III)

October 12, 2010

Last week, we discussed how we could generate uniform random points in a triangle using a (tiny) bit of linear algebra, mostly the parallelogram rule, and a random variable uniform on [0,1]. It required a tiny bit of math and was computationally very simple.

This time, let us see how we can generate uniformly distributed random points on a sphere.
