Splash is an alternative approach to traditional top-left to bottom-right scanline image/frame rendering. It sorts the pixels of a frame in order of significance, and paints them guided by weighted rows and columns. The longer the rendering, the higher the detail, making it highly tolerant against data corruption. A full frame is lossless, truncated frames are lossy. Splash shines in it’s lossyness.<p>Inspiration: The fractal zoomer rendering engine of my other project [<a href="https://rockingship.github.io/jsFractalZoom" rel="nofollow">https://rockingship.github.io/jsFractalZoom</a>] wondering how it would be with real-world imagery instead of procedural generated content, and how I believe my brain perceives movement: you pay attention first to areas with heavy contrast changes because they are most likely caused by moving things.<p>Explanation by example:<p>STARSHIPS:<p>14 second clip with high contrasts and lots of movement in different directions. Top video show frames from the a 1212x510 input source and rendered top-left zig-zag to bottom-right. Each frame contains 618120 pixels, Splash takes 618120 self-chosen pixels spread over 6 frames and paints them in the bottom video. Top and bottom both have identical pixel data rates.<p>[<a href="https://rockingship.github.io/splash-media/starships/starships-1212x510-OU-crf18.mp4" rel="nofollow">https://rockingship.github.io/splash-media/starships/starshi...</a>]<p>GTA:<p>Lets explore the extremes by assuming there is data corruption and only the first 1% of the frame was recoverable. Left is Splash and what it’s continuous paintbrush rendered. Right would be the traditional first 9 scanlines of the input making if effectively unrecoverable. To give traditional at least a fighting chance, the frame is downscaled 100 times to 90x50 and upscaled again to original 900x506.<p>[<a href="https://rockingship.github.io/splash-media/gta/gta-sbs-1800x506.webp" rel="nofollow">https://rockingship.github.io/splash-media/gta/gta-sbs-1800x...</a>]<p>FFMPEG:<p>The project includes a patch for ffmpeg [<a href="https://rockingship.github.io/splash/20230313-splash_codec.patch" rel="nofollow">https://rockingship.github.io/splash/20230313-splash_codec.p...</a>].
