For 3D work in PDL, there's PDL::Graphics::TriD to visualise things in various ways.

There's also PDL::Graphics::TriD::Quaternion, not hyperlinked because not indexed by MetaCPAN; it's in a slightly rough state (e.g. doesn't have the obvious overloads), but is used by the UI interaction code, so actually works very well.
