Hi Paolo,
This would probably be quite a different way of dealing with the data
source. I suppose the idea would be to fetch all the points at once and
store them in a kd-tree. Otherwise, refreshing the canvas would take
ages to refresh.
The laslib [0,1] (from lastools) is LGPL.
But there is also liblas [2] which is available on Osgeo4W and has
debian packages.
The code is on github [3], there is the licence info:
Redistribution and use in source and binary forms, with or without
modification, are permitted provided that the following
conditions are met....
Cheers,
Denis
