Simple approximate nearest neighbor (KNN) search for OpenFrameworks.
After writing a couple (shitty) KNN implmentations from scratch, I figured I'd leverage some smarter people's work for an easier and faster implementation. The goal of this library is to provide a simple, easy-to-use interface, by favoring convention over configuration. Therefore, it currently uses the most basic algorithms provided by nanoflann, but could easily be extended to allow more advanced functionality (hopefully without sacrificing ease of use).
Copy examples/ofxAnnBasicExample to your OF apps directory and build and run it. Read the source.
