Actually i liked the idea you used, Without using normals and many much complicated stuffs .
Actually i have more than 57000 points , and i only want to consider those points which are far away from each other....
If you provide the answer immediately , it would be very useful to me.... please...

you can use clustering algorithm (K-means probably not good since K is large and not fixed, I would choose DBSCAN) first, and then pick any one dot from each cluster, that will be "those points which are far away from each other"
