What's Changed

Significant enhancements to the KDTree (#769):

  • pynbody's sphere filters now make use of the KDTree to greatly enhance extracting spheres from large simulations.
  • KDTrees will not automatically be built, so you should call f.build_tree() before f[pynbody.filt.Sphere(...)] to obtain the speed-up. Building the tree takes a while, so this is only worth doing if a large number of spheres will be extracted.
  • KDTrees are now built in parallel, significantly speeding up operations that need them (such as SPH smoothing)
  • KDTree data is now stored in numpy arrays, so it can be inspected from python and also can be stored in shared memory
