voronoi3d edges

Hi all,

I'm wondering if there are suggestions on using C# in GH to generate voronoi cell (or tetrahedral) edges given a point cloud, without generating the cells themselves as breps?

(I saw something that might be of relevance in Nik's use of the Tetgen library here:

Thanks a lot!
