My objetive is to calculate overlapping between spheres. What is the minimum number of points to allocate in the surface of a sphere, so we can perform numerical integration over each sphere with the highest possible accuracy? Should they be distributed randomly of following some criteria? Which are the best algorithms for this?
PS: A clear example of what I am looking for is related to this. Lebedev uses some idea to generate up to 30 something points which warranties some good accuracy
