There are N number of points in the 3D. The co-ordinates of the points are not known. Pairwise distances between all the points are known. If the location of the first 4 points are ascertained, how can the co-ordinates of the remaining points be determined? Is there any clever algorithm for large datasets (i.e. N ~ 10^6)?
