Well hello everyone, I'm in a bit of technical trouble. I'm sure everyone has seen the large LED displays in China that have been all over the web for the past few months. Well, I'm trying to do the same thing. The basics are simple enough, take a photo from a predetermined vantage point, reconstruct geometry and camera, do the whole animation thing, render from reconstructed view and reproject onto the reconstructed geometry to bake onto a UV map. This has always worked for me in the past, but with screens that have right angles. Now I'm facing a curved screen, like in THIS example. My goto method has just stopped working. I can't get my angles right, everything seems bent as heck in real life. The funny thing is things DO line up when I take a photo of the screens from the predetermined vantage point. My guess is that projecting on a curve isn't as straightforward as it might seems, but I've trying for a while now and I had little luck until now... In my hour of despair I turn to you, oh great wizards of vfx. Is there something I'm missing? Do I need another workflow? I'm eager to listen to your wisdom! Cheers!
