title: Can anyone explain the difference between organized and unorganized point cloud?
body: <p>What is the difference between organized point cloud and an unorganized one?</p>
  
  <p>Am I right in thinking that a point cloud is a column of [x,y,z] values? Than what is the difference in the structure of the point cloud if its organized or unorganized ?</p>
  
  <p>How does it affect the later processing steps like filtering, normal estimation, registration etc ?</p>
  
  <p>Thanks,
  Sai</p>
