title: Is Morton code the most efficient for higher dimensions?
body: <p>For my current input data, which is points in 3D, I'm using <a href="https://stackoverflow.com/questions/1024754/">Morton code</a> to improve the cache coherence when accessing the point list.</p>
  
  <p>I have some other data that is 6D and 7D. Is Morton code still a good technique for such dimensions? Or are there any other techniques? The other space filling curve techniques were more complex to compute than Morton in 3D itself, I'm wondering if folks use an alternative technique for 6D/7D or higher.</p>
