Greetings from Perth, if I understand you correctly you want to create graphics
for a cylindrical display. I have done this for full 360 degree displays
including those that are additionally stereo. What you generally need to do is
twofold
1. Create your content as cylindrical panoramic images, I suggest just panoramic
of the right vertical field of view to match your projection environment. See
more details on the equations see
   http://local.wasp.uwa.edu.au/~pbourke/projection/stereopanoramic/procedure/

2. You then need to geometry correct (warp) the images so that when projected
using a (perspective) projector you get the right image on the cylinder. See
   http://local.wasp.uwa.edu.au/~pbourke/projection/cylinder/
and
