Voronoi 3D question - differences GH0.8 and GH0.9

Hi there,

I am relatively new to Grasshopper and found some examples about a 3D Voronoi diagram which I tried to rebuild to understand it. Uunfortunately, it was an example for GH 0.8, but I have GH 0.9.0076, and some boxes are not available or changed. Can you help me which functions I should use instead?

I circled the trouble-makers.

Thanks a lot for your help.
