Chris,

The Tachyon renderer doesn't have the options for omnidirection
projection or 3D. Using Tachyon-Optix it will do both of those in the
one step, left and right views combined one above the other in the
same image, then the required projection of the scene so that it can
be projected correctly to give the 360 view.

I have used Tachyon to generate high resolution 3D animations, just
need to do the left and right views separately then combine them.
Catch ya,
