===Notes 2===
* '''TODO compare quality of two methods'''
* according to Mike's email mesh should be around 1M vertices
* in some cases boundary recovery reached a point of non-developed code. Rerunning created a different surface mesh and CDT3D was able to continue.
* commit <code> 912b8d5ec5b171ebf20bc6a61b9f7fe572f3d3d5 </code>
* parameters <code> --met=1 --meval=3 --mrecm2=1 --mrec4=1  --nadapt=1 --reconstruct=1 --malign=0 --mpp=2  --qstatr=1 --outmesh=${NAME}.meshb --ndfs=0 --nthreads=$THREADS --nbuckets=20*NTHREADS --nthreadsaf=20*NTHREADS --nbucketsaf=20*NTHREADS --blockmul=500000 --nqual=0 --nminpts=30 --ordt=0 --pardeact=1 --mdse=0 </code>
