title: How to resize an existing point cloud file?
body: <p>I am trying to enlarge a point cloud data set. Suppose I have a point cloud data set consisting of 100 points &amp; I want to enlarge it to say 5 times. Actually I am studying some specific structure which is very small, so I want to zoom in &amp; do some computations. I want something like imresize() in Matlab.
  Is there any function to do this? What does resize() function do in PCL? Any idea about how can I do it?</p>
