- KaiserPro 13y agoUsing 3d space to represent movement of the textures. Currently a frame is split up into blocks, and they are moved about in 2d (X&Y). Using a 3d model of the movement would theoretically gain you some savings, as it would require less refreshing of the moving blocks.
- epeus 13y agoQuite. You can define a textures+trimeshes+motion format and have the decoder be well defined, then have encoders compete to do better, as we have seen with the 2d codecs. Clearly starting form something in GL, like a game walkthrough (How much of youtube is that?) is easier than starting with Bladerunner. A Pixar movie would be somewhere inbetween.
- cromwellian 13y agoObject-based encoding has long been discussed within the MPEG community. MPEG-4 included VRML as a sort of hack for scene based compositing and Structured Audio Orchestration Language et al, as a parallel. I saw early whitepapers where they had planned even to do things like recognize people's faces, and deduce geometry, thereby separately compressing a person in the foreground vs background (use case: conference calls, news anchors, etc) As for whether it is possible to deduce 3D structure 2D, there's been some progress in that regard, check this out: http://www.youtube.com/watch?v=CZiSK7OMANw http://www.youtube.com/watch?v=CZiSK7OMANw

- jlgreco 13y agoWould companies that produce computer animated movies be willing to risk exposing their 3d/texture assets like that? If even low-quality "pre-rendered"^ versions of those fell into the hands of the community then those companies would basically have to deal with a bunch of people using their stuff (probably mostly fair-use covered parody stuff on youtube, but also high quality Chinese knockoff movies and the like.) ^ You would have to pre-render that stuff in some way first, wouldn't you? The actual source assets for those movies are absolutely massive and do not render in real time.
- epeus 13y agoThe world is 3D. I bet the last few films you saw had extensive 3D modelled scenes in them. I bet all the video games you play have 3D cutscenes.
