WebOct 31, 2011 · Then I would suggest ZCW angles, which are equally distributed all over the sphere and fast to calculate. Other methods are TheSydneyOperaHouse (SOPHE) and Repulsion. (search for repulsion.c) The repulsion method is quite good but slow: It iteratively distributes points evenly over a sphere. Fortunately it has to be done only once.

WebMay 3, 2011 · 2 Answers. If you measure distance along the path it is no different from a straight line. If the length is L and you want n points (including the ends) you put a point at one end and every L n − 1 along the way. If you measure distance as straight lines between the points there is no guarantee of a solution, but you could just start with ... WebThe following describes two (inefficient) methods of evenly distributing points on a sphere.

WebMar 16, 2016 · In order to plot a point on a sphere's surface, we need two numbers: the colatitude, φ and the longitude, θ. We could use the latitude, which is given by 90°− φ, but colatitude is the conventional quantity to deal with. Now, we will make the simplistic assumption that we can use a uniform distribution for both the colatitude and longitude. WebIt is well known that the sequence x n = n m ϕ mod m where ϕ = 1 + 5 2 is the golden ratio can be used to generate an arbitrary amount of evenly spaced points in the interval [ 0, m).
