I along with Ashwin had done a graphics project in which we were supposed to build octree efficiently and to answer near queries for nodes.
The project is here.
Please go through the Readme.
One possible set of instructions to run the code is as follows
1) make
2) make random
3) ./random > input.txt
10
3
4
4) cat input.txt
5) ./octree input.txt
1 (for selecting a node)
1.80277 1.10057 1.23684 (giving the node which basically select any one point from the input.txt ...this is the first random point which was generated)
thats it .... a window will open and use arrow keys to navigate
i = zoom in
o= zoom out
