I'm looking for efficient data structures for storing 3d points (x,y,z). The effect of storing in at the points in a data structure should generate a more memory efficient structure and a faster search for a specific set of coordinates. The 3d points is mapping to a specific ID so it should be able to keep track of each set of coordinates I'm looking for any implementation which is available.
x, y, z gives the cartesian coordinates of each node.
id x y z
1 14.566132 34.873772 7.857000
2 16.022520 33.760513 7.047000
3 17.542000 32.604973 6.885001
4 19.163984 32.022469 5.913000
5 20.448090 30.822802 4.860000
6 21.897903 28.881084 3.402000
7 18.461960 30.289471 8.586000
8 19.420759 28.730757 9.558000
The number of coordinates will be huge maybe around 1 000 000.
Thanks in advance!
