I found what I need.
Geogram geogram_demo_Delaunay3d
They are called Delaunay 3d but this is not the Delaunay algorithm! Here is Delon’s algorithm → MakarovDs777/Delaunay-triangulation-in-a-3d-cube-python: Триангуляция Делона в 3-х мерном кубе.
And what they call it Lloyd relaxation.
And what they call it is Lloyd relaxation, not Delaunay 3D.
