role: prerequisite
location: https://pkg.cppget.org/1/stable
# trust: ...

If the stable section of cppget.org is not an option then add this Git repository itself instead as a prerequisite.

Add the respective dependency in your project's manifest file to make the package available for import.

nanoflann 1.3.2: Released Nov 5, 2020

• Add optional argument for Eigen matrix layout commit.
• Throw exception on malloc failure PR #126.
• Respect GNUInstallDirs in CMake install rules PR #131.

nanoflann 1.3.1: Released Oct 11, 2019

• Fixed bug in KDTreeSingleIndexDynamicAdaptor. See: https://github.com/jlblancoc/nanoflann/commit/a066148517d16c173954dcde13c1527481b9fad3
• Fix build in XCode.
• Simplify CMakeLists for Eigen example (requires Eigen3Config.cmake now)
• Avoid setting cmake global executable build path

nanoflann 1.3.0: Released Aug 28, 2018

• Instructions for make install for Linux and Windows (Closes #87).
• Fix all (?) MSVC conversion warnings (Closes: #95).
• Avoid need for _USE_MATH_DEFINES in MSVC (Closes: #96)
• Eigen::Matrix datasets: now uses std::cref() to store a reference to matrix.
• GSOC2017 contributions by Pranjal Kumar Rai:
  • Support for dynamic datasets.
  • Support for non-Euclidean spaces: SO(2), SO(3)

nanoflann 1.2.3: Released Dec 20, 2016

• Fixed: split plane now correctly chooses the dimensions with the largest span. Should lead to more optimal trees.

nanoflann 1.2.2: Released Nov 10, 2016

• knnSearch() now also returns the number of valid points found.

nanoflann 1.2.1: Released Jun 1, 2016

• Fix potential compiler warnings if IndexType is signed.
• New unit tests comparing the results to those of brute force search.

nanoflann 1.2.0: Released May 5, 2016

• Fixed: many classes constructors get const ref arguments but stored const values.

nanoflann 1.1.9: Released Oct 2, 2015

• Added KDTreeSingleIndexAdaptor::radiusSearchCustomCallback() (Based on a suggestion by Yannick Morin-Rivest)
• Better documentation in class headers.
• Cleanup of unused code.
• Parameter KDTreeSingleIndexAdaptorParams::dim has been removed since it was redundant.

nanoflann 1.1.8: Released May 2, 2014

• Created hidden constructors in nanoflann class, to disallow unintentional copies which will corrupt the internal pointers.
• Fixed crash if trying to build an index of an empty dataset.

nanoflann 1.1.7: Released Aug 24, 2013

• Two internal containers are now automatically defined as fixed-size arrays if the problem dimension is known at compile time, improving efficiency. The new/modified datatypes are: KDTreeSingleIndexAdaptor::BoundingBox, KDTreeSingleIndexAdaptor::distance_vector_t
• Fixed compilation with GCC 4.8 and C++11 enabled (Thanks to Simon Praetorius).

nanoflann 1.1.6: Released May 14, 2013

• Fixed warnings about unused parameters.
• Fixed L1_adaptor.accum_dist(), which implemented L2 instead (Closes #1)
• Fixed wrong typedef in KDTreeEigenMatrixAdaptor<> for IndexType!=size_t (Closes: #2)

nanoflann 1.1.5: Released Mar 25, 2013

• Fixed: Memory pool wasn't freed after each call to buildIndex()
• GCC: Added -isystem flag to gtest headers to avoid pedantic warnings.

nanoflann 1.1.4: Released Jan 11, 2013

• Fixed compilation with Visual Studio 11 (MSVC 2012).
• Fixed compilation of gtest with VS11 and its _VARIADIC_MAX "bug".
• Added a security check to launch an exception if searches are attempted before buildIndex().
• New example to demonstrate save/load the index to files.
• save/load methods exposed as public.

nanoflann 1.1.3: Released Jun 6, 2012

• GTest sources are now embedded, due to the changes in newer Ubuntu packages which don't carry the precompiled libs.
• Added asserts to detect whether the user passes NULL as query points.
• New method RadiusResultSet::worst_item()
• New method RadiusResultSet::set_radius_and_clear()
• Avoid potential collision of min/max macros with <windows.h>
• Removed unneeded #include's of std headers.
• New sample code for vectors of vectors.
• Fixed building of tests for MSVC in Windows.
• Allow manually setting the path to Eigen3 (mainly for building examples under Windows).

nanoflann 1.1.2: Released May 2, 2012

• Better documentation and added graphs of a benchmarking for helping choosing "leaf_max_size".
• Now KDTreeSingleIndexAdaptor::buildIndex() can be called several times even when the dataset size changes (Thanks to Rob McDonald for reporting!)

nanoflann 1.1.1: Released Feb 1, 2012

• Some fixes to kd_tree index and L1/L2 metrics to allow distinct types in data elements and in the distances. This is mainly to permit elements being vectors of integers (e.g. uint8_t) but distances being real numbers.
• Examples and unit tests have been corrected to use template arguments instead of being hard-wired to "float" data types (Thanks Thomas Vincent for noticing!).

nanoflann 1.1.0: Released Dec 15, 2011

• Fixed warnings for MSVC and for GCC with "-Wall -pedantic"
• Updated performance tests to work with the final nanoflann code (they were written for a very early version).
• All main classes now have new template arguments for the type of indice, which now defaults to "size_t" instead of "int". In case this breaks backward compatibility in user code, especify "int" to override the default template arguments, although "size_t" it's recommended.

nanoflann 1.0.0: Released Aug 30, 2011

• Initial version
