Well, there are lots of possible ways .... since you posted this to the PovRay
group, one way is to render a panoramic image of your scene using PovRay. Then
create a second model that consists of just a cylinder, the same dimensions as
the cylinder you plan to project onto and with your panoramic image applied as
a texture. Create a camera at the same location and of the same specifications
as your data projector. If you render this second scene then you will have the
correctly warped result. Note that since PovRay doesn't readily do offset
frustums then you need to get up to tricks like this to get the offset frustrum
your data projector creates.
