Dear Boyu Meng,
the number of bins in your usrbin structure is too large, there is not
enough space in memory to contain all of them.

To solve the problem, you will have to reduce the number of bins. Tere
are two options:
- Use larger bins. This can be a problem if your bin size (dimension of
the usrbin divided by number of bins) becomes larger than the voxel size
- Cover only one part of the voxel geometry with the usrbin
Or combine the two: a small volume usrbin with small bins, aand a second,
large voulme usrbin with large bins.
Hope this helps
