MLSGPU is software that constructs a triangulated mesh from a point cloud. It is designed to handle massive point clouds (billions of points), and uses OpenCL for GPU acceleration. It implements the method described in the paper Moving Least-Squares Reconstruction of Large Models with GPUs.
The documentation can be found at http://bmerry.github.io/mlsgpu. For the very impatient (who have all the dependencies installed), the installation process is
python waf configure --variant=release python waf sudo python waf install
