Tailoring vectorial optical fields (VOFs) with polarization singularity along the propagation path advances development of fundamental physics and communications. This study demonstrates that spin-multiplexing metasurfaces can introduce a seamlessly varying related phase difference, enabling generation VOFs longitudinally evolving distributions. By superposing two orthogonal circularly polarized components, we achieve dynamic evolution from radial to azimuthal path. Experimental results confirm observed distributions align trajectory on higher-order Poincare spheres. The design strategy offers substantial flexibility for crafting arbitrary orders. Further, show dual distinct axis. approach opens new avenues applications in light-matter interactions, complex structured light generation, advanced engineering.
