I’m trying to warp an image so that it will appear undistorted when projected onto a horizontal cylinder. The projection is 1:1 — no magnification — so the image height is slightly less than the cylinder diameter. In a ray tracing the lines would all be parallel. I’ve made a couple of attempts at warping it manually, which showed that it could work, but I was wondering if there was a more accurate way to do it. Thanks!
