Detailed Description

template<typename DistanceType>
struct flann::cuda::RadiusResultSet< DistanceType >

fills the radius output buffer. IMPORTANT ASSERTION: ASSUMES THAT THERE IS ENOUGH SPACE FOR EVERY NEIGHBOR! IF THIS ISN'T TRUE, USE KnnRadiusResultSet! (Otherwise, the neighbors of one element might overflow into the next element, or past the buffer.)
