pre Same thing. If the output is not interactive, a raytracer is the way to go as you can cast/project rays per pixel in whatever panorama projection you wish. With 4x4 matrix based projections that realtime engines do, you are limited to linear projections that can only vary per vertex and not per pixel but are typically constant for the whole frame. So the only way to do it will be by patching a number of such projections, which is what cubemap does, as well as your monster-approach. The difference is only in number of pathces.
