Issue Details

I used the source code for surface reconstruction from point cloud and the kitten.xyz was reconstructed nicely but when I import another geometry of my own, the poisson reconstructed surface does not even close up the points, im wondering what could possibly be the problems that caused it? This point cloud supposed to be a section of a tunnel as shown below

Your point set is too sparse for this kind of algorithm. Also it will not produce a mesh going through your points.

Is this point set too sparse as well? Because the reconstructed surface looks like this

Also, for the simplification portion of code, it seems like it always says 0 points removed after simplification even when i purposely make the duplicate points in the point set, and even if I pass in a 300,000 points for a point set, it still says 0 points removed after simplification.
