Actually that is exactly what people did in the aformentioned Organica modeler in the 90's. Yes, using a GUI modeling app but that is not a requirement here. Some vids that show what is possible with a text editor and not much effort (if you have a lib of ready-made SDF components you string together in code): https://www.shadertoy.com/view/3lsSzf https://www.shadertoy.com/view/3lsSzf https://www.shadertoy.com/view/WsSBzh https://www.shadertoy.com/view/WsSBzh So yeah, I'd disagree with the 'nobody'. I wrote shaders for blokcbutser VFX as part of my job for over a decade. We regularly did some very complex SDF stuff there simply because we had to. I think Gilles Tran especially would be the kind of person who'd do that sort of stuff[1] if the object in question was central enough to the image. Which the motion blurred human figure in the "The wet bird" was not. [1] http://www.oyonale.com/modeles.php?lang=en&page=6 http://www.oyonale.com/modeles.php?lang=en&page=6
