How to sample fixed number points from the mseh surfaces?

[Haiyan-Chris-Wang]

@TonythePlaneswalker As you mentioned in the paper, to get the complete groud truth point cloud, you sample the point cloud from the mesh model. I am using the mesh_sampling.cpp code to do sampling. However, after I set the -n_samples = 100000, the points number of the output point cloud are not 100000, it still could be different numbers such as 95429. Do you have any idea about the problem.?

Thanks for your help!
