180 degree mode?

[Fieora]

Is it possible in the current framework to project an image/video on to a hemisphere for 180 footage?

UPDATE:
I tried to access the
panorama.object.geometry.parameters.phiLength
and
panorama.object.geometry.parameters.phiStart
but setting those didn't achieve the same as when I set them on a generic sphere

I figured this one out, for future reference:
If you need to change the geometry of the object you need to create a new geometry and assign it as a whole instead of just the piece you want to change.
