Any idea how to implement the 3D delaunay in Grasshopper?  I have been working on a work around that involves using Tetgen and then importing the resulting mesh back into Rhino however this process is clumsy and the resultant mesh is just too complex to work with in Grasshopper.  Ideally I'd like to be able to do this to a fairly large (thousands) point cloud with the aim to create a mesh approximating the concave hull.

Thanks.

You know Daniel that making 3d alpha shape will require to do 3d Delaunay first... I need some time to do that.

Nice work! Thanks for sharing...
and of course, you know I have to ask - 3d next ? ;)
