{
auto c = star.getCoords();
std::vector<std::vector<int>> idx;
std::vector<std::vector<double>> dists;
double t2 = threshold * threshold;

{
return v != star;
};
auto xform = [this](int i)
{
return byIndex().at(i);
};
/* lol, iterators */
auto xbegin = make_transform_iterator(idx.front().begin(), xform);
auto xend = make_transform_iterator(idx.front().end(), xform);
auto begin = make_filter_iterator(pred, xbegin, xend);
auto end = make_filter_iterator(pred, xend, xend);
return StarSet(begin, end);
}示例2: nearestNeighbor
Star StarMap::nearestNeighbor(const Star& star, double threshold) const
{
auto c = star.getCoords();
int index[2] = { 0 };
double dist[2] = { 0 };
flann::Matrix<int> i = toMatrix(index, 1, 2);

spatial_index_->knnSearch(toMatrix(&c), i, d, 2, flann::SearchParams());
return (dist[1] < threshold*threshold) ? byIndex().at(index[1]) : Star();
