Thanks David for your quick reply,<br>
<br>
I gave a look what the stratified sampling algorithm you've mentioned, but I still have some questions:<br>
As I understood, the "Level" option controls the density of the points, but how is this done? Is it possible to specify the sampling step? Does this method works for upsampling or only for downsampling?<br></blockquote>
