I've always wished Pixar would do what Id software did, releasing an Open Source version of some small portion of their movies for analysis, like this Moana scene. Because the question on my mind is, given the improvements in rendering, there's some year in which we can now render in real time, what took a long time for Pixar to render. So, what is it? I believe I read that creating the 3D version of Toy Story ran at 24 fps, averaged across the entire film. So, basically, we already crossed the threshold for Toy Story. (But maybe that was only if you have a rendering farm?) So, where are we at? Could we render a plausible Toy Story in real time now? Bug's Life? Monsters Inc?

All Blender movies can be downloaded for this reason: https://cloud.blender.org/open-projects https://cloud.blender.org/open-projects Last month they discovered a bug in Blender that was the cause of very slow hair rendering. The fix dropped render times for some scenes from 4 minutes to 40 seconds. So it can indeed be useful to check if things can be improved for old movies. But I am not sure realtime is an option right now. Most movies also use post processing per frame wich also takes some time.

The Kingdom Hearts games have areas based on various Disney IPs, and the last one came out fairly recently so it makes for a nice comparison Pixar Toy Story vs Realtime Toy Story: https://www.youtube.com/watch?v=tkDadVrBr1Y https://www.youtube.com/watch?v=tkDadVrBr1Y Disney Frozen vs Realtime Frozen: https://www.youtube.com/watch?v=q8vCQqg6SYg https://www.youtube.com/watch?v=q8vCQqg6SYg

  KH3 from 3 years ago clearly is missing dynamic shadows (e.g. when Woody moves his head, the lighting around his face changes based on shadows cast by his hat and nose). Also the original toystory appeared to have at least 2 surfaces for reflecting off of the floor while I didn't see any reflections off of the floor in KH3. Granted that's 3 years old now. Also, TS was definitely rendered higher than 1080p to make the transfer to 35mm film for large screens.

    Toy Story was rendered at 1536 × 922 pixels, 48 bits per pixel. https://stack.com.au/film-tv/movie-review/toy-story-4k-ultra-hd-review/#:~:text=When%20Toy%20Story%20was%20made,4K%20at%204096%20x%202160 https://stack.com.au/film-tv/movie-review/toy-story-4k-ultra....

      Lower than I expected; I wonder how they transferred it to film? (presumably not with square pixels!).
