Uniform points on a sphere

Charged conducting sphere. Sphere of uniform charge. Fields for other charge geometries. The electric flux is then just the electric field times the area of the spherical surface. The electric field is seen to be identical to that of a point charge Q at the center of the sphere.Dec 30, 2008 · sphere_122.xyz 122 points on the surface of a sphere; sphere_482.xyz 482 points on the surface of a sphere; sphere_spiral_700.xyz, 700 points spiral around the surface of the unit sphere; sphere_spiral_700.png, a PNG image of the data. teapot_306.xyz, 306 points on a teapot;

sample points uniformly on a sphere by dividing an icosahedron(the largest convex regular polyhedron). Samples 3D points on a sphere surface by refining an icosahedron, as in: Hinterstoisser et al., Simultaneous Recognition and Homography Extraction of Local Patches with a...In this tutorial, we will plot a set of random, uniformly distributed, points on the surface of a sphere. This seems like a trivial task, but we will see that the "obvious" solution is actually incorrect. We will start off with this incorrect method, and then improve it to be correct.How can one create a uniform solid-angular distribution of vectors in 3D space from a common origin, or in other words a grid of points on the surface of a sphere wherein the points are equidistant from each other?What is the probability that n randomly chosen points on a sphere will all lie in a single hemisphere? More generally, we can consider the same question for points chosen randomly from a uniform distribution on a d-dimensional spherical surface, denoted as Sd. The trivial case is S0, which...
