@Tharwen Notice how in a circle there are more points at radius 0.9-1.0 than at radius 0.0-0.1. random()+random() generates radii more likely to be around 1.0 but lie in the range 0.0-2.0.
In spherical coordinates, is the radius, is the azimuthal angle, and is the polar angle. A tempting way to generate uniformly distributed numbers in a sphere is to generate a uniform distribution of and , then apply the above transformation to yield points in Cartesian space , as with the following C++ code. #include<random> #include<cmath>

Some points: 1. arccos(-1..1) normally gives the range 0..pi, so I would be inclined to subtract pi/2 instead of pi, to get a number in the range -pi/2 .. pi/2 which is how a geographer would present the angle. Actually I think this change is required, because the current answer will always give negative z. 2.
ANGLE POINT – A point in a survey where the alinement or boundary deflects from a straight line. APEX – In mining, the outcrop of a vein or the highest portion of a fold in a vein. APPEAL – A process of civil law origin that entirely removes a controversy to an appellate court for the purpose of obtaining review and possible retrial.
To get the best cross-browser support, it is a common practice to apply vendor prefixes to CSS properties and values that require them to work. For instance -webkit-or -moz-. We offer two popular choices: Autoprefixer (which processes your CSS server-side) and -prefix-free (which applies prefixes via a script, client-side).
