However, conventional multicasting solutions are confined to one\u2010 or two\u2010dimensional operations with limited diversity; multichannel, multimode implementations in three\u2010dimensional (3D) vector space remain largely unexplored, which promises to maximize throughput. Herein, for the first time we develop a volumetric CVB multicasting strategy that introduces 3D multichannel array modes as information carriers. By coherently merging a vectorial Dammann vortex grating and a vectorial Dammann vortex zone plate on a minimalist spin\u2010multiplexed phase\u2010modulation metasurface, array degrees of freedom in both the transverse plane and longitudinal depth are independently regulated, thereby unlocking a 3D multichannel CVB lattice with sufficient mode diversity. As demonstration, we achieve a 3D CVB array generator with an operational dimension of 3\u00a0\u00d7\u00a03\u00a0\u00d7\u00a05, and 400\u00a0Gbit\/s quadrature phase shift keying signals are successfully distributed to up to nine distinct spatial nodes with bit error rates of 10\n                    <jats:sup>\u22126<\/jats:sup>\n                    . This work provides a compact and scalable platform for volumetric vector\u2010field engineering, opening new pathways for multidimensional optical field manipulation and complex optical node interconnection, which may accelerate advances in optical edge data processing and short\u2010reach communication networking.\n
