{{sketch.parentSketch.title}} by {{sketch.parentUser.fullname}}.
A fast method of producing an arbitrary number of equally distributed points around a sphere. This is accomplished by drawing a fibonacci spiral (similar to sunflower seed pattern) that maintains constant surface area.
n = number of points
phi = (sqrt(5)+1)/2 - 1
ga = PHI * TWO_PI
for each point i (1..n)
longitude = ga*i
latitude = asin(-1 + 2*i/n)
As written, the sketch constantly adds new points to the sphere. Click to toggle this feature, so you can examine the point distribution.
