ok... im working on laser scanner cloud of points... the model im
working with is something like a plane...
i need to project the points over a straight plane so i think it would
be a good idea to use the best-fitting plane for this.
maybe is there a function to decimate the points?? so i can use this
function:

starting it on 25000 points give an "out of memory"...
sorry for my english :-)
thanks
