nanoflann: a C++11 header-only library for Nearest Neighbor (NN) search with KD-trees
I spent some time debugging an access violation, only to find out the executable wasn't instantiating the correct classes for nanoflann. Due to how c++ seems to work, the same...
I can't seem to be able to find a way to use multiple threads while using `KDTreeEigenMatrixAdaptor`. I looked at the class constructor and it seems to be quite overlooked....
Hi, I am trying to implement an algorithm ICP style. And to find correspondences between the two d-dimensional point sets (assuming same number of points per set). However because I...
```c++ KDTreeVectorOfVectorsAdaptor ``` or ```c++ KDTreeVectorOfVectorsAdaptor ``` Does it work?
``` nanoflann::KdTreeFLANN::Ptr kdtree = std::make_shared(); if (!kdtree) { std::cerr radiusSearch(search_pt, 2.0, searchIndexes, distances); } ``` The size of searchIndexes is always equal to 1 during the for-loop(I have checked the...
Hi, I've created a KDTree Class, I call, from main.cpp, another .cpp file to create the KDTree object and then return to me the KDTree object created for searchs, but...
Does nanoflann have any facilities for finding all points within a box? To give a 2D example, we may be looking to list all $(x,y)$ points so that $x \in...
Hi, in this line https://github.com/jlblancoc/nanoflann/blob/923c2ac16a955317054c296d298425d33c0cb9de/include/nanoflann.hpp#L1771 The input is named `radius`, but in the `RKNNResultSet`, what it expects is `maximumSearchDistanceSquared`. Is this the intended behavior?
Hello, I'd like to pre-sort the point data I have prior to building an index, and then have the results of radiusSearch return indices in the same order. Any idea...
