Massive PLY file, what software?

This may not be the correct forum, but I have a question about 3D point cloud files and not sure where to ask it.

I have a massive (6GB) PLY file and I can't find an editor to view it. I tried meshlab but the program promptly crashes.. I don't even get to view the contents.

Does anyone know of a Mac viewer that will enable me to view the data? Anyone know of a decimating software that will reduce the total point count?

Any help or advice would be greatly appreciated.
Thanks.

I really want to try this, but there are no binaries available. Users have to compile their own version and this is a little over my head.
