  Interactions in a spin-polarized ultracold Fermi gas are governed by $p$-wave
collisions and can be characterized by the $p$-wave scattering volume. Control
of these collisions by Feshbach resonances is hampered by huge inelastic
losses. Here, we suggest non-resonant light control of $p$-wave collisions,
exploiting the anisotropic coupling of non-resonant light to the polarizability
of the atoms. The $p$-wave scattering volume can be controlled by strong
non-resonant light, in close analogy to the $s$-wave scattering length. For
collision partners that are tightly trapped, the non-resonant light induces an
energy shift directly related to the generalized scattering volume. This effect
could be used to climb the ladder of the trap. We also show that controlling
the generalized scattering volume implies control, at least roughly, over the
orientation of the interparticle axis relative to the polarization direction of
the light at short interatomic distances. Our proposal is based on an
asymptotic model that explicitly accounts for the anisotropic dipole-dipole
interaction which governs the ultracold collision dynamics at long-range.
