It could be done with something like OpenImageIO which is geared towards tiled mip-mapped textures (in fact I believe they do this with the FFMPEG backend already, but this was made after my experiment).Alex Fullerhttps://www.blogger.com/profile/11925597315527622030noreply@blogger.comtag:blogger.com,1999:blog-7395797351911594965.post-4396291439703732982015-12-06T19:45:31.948-08:002015-12-06T19:45:31.948-08:00Very interesting.

I started messing with Fraps and VirtualDub, because it was an easy and quick way to get tons of similar data file pairs. <br />Rich Geldreichhttps://www.blogger.com/profile/14358203173986928600noreply@blogger.comtag:blogger.com,1999:blog-7395797351911594965.post-19469099839178439052015-12-06T19:35:50.292-08:002015-12-06T19:35:50.292-08:00Kind of reminds me of an experiment I was doing wh...Kind of reminds me of an experiment I was doing where I'd get, say, a 1024x1024 texture and then compressed it using h264 or vp9 into a 128x128 video clip of 64 frames, so utilising the video encoder's delta frames. It actually works out well for some textures, it might work well if DXTC/ASTC/PVRTC could be delta'd into tiles this way too.Alex Fullerhttps://www.blogger.com/profile/11925597315527622030noreply@blogger.com
